1 + 4 = 5
2 + 5 = 12
3 + 6 = 21
8 + 11 = ?

... and it is 40.

what

92

19 ;)
[for the format, I'm going with 96]

... and it is 40.
No seriously this is the answer. Now you guys just have to figure out why. Everyone will be kicking themselves later. (no I didn't look it up. My brain just works this way.)
-
... and it is 40.
No seriously this is the answer.
Maybe.

96

There is no maybe. :lol It is what it is. The math is right there. Don't make me explain it before it runs it's course. I'm trying to be nice here.
-
Yeah, I'm not seeing 40 anywhere. Hopefully there's an explanation in 8 hours when I clock out. :p
-
I got an answer that others also gave, but I'm trying to figure out how to prove if it's the only one. It seems like it is, but thats not a good enough reason.
-

I'll PM you if it starts to bug you enough.
-
I see both.
-
If everything in the OP remains true, there can only be one answer.
-
40 is the obvious answer, but there's probably more than one answer because the obvious solution is never the right one with these questions.

You'd think it's obvious but the older I get the more I realize how unique my brain is compared to other people. You clearly share the same flair for processing trick logic questions. I bet there's a tremendous number of people who never even understand where 40 comes from.
-
Got it.
-
I instantly got 40. Can someone explain how they're coming up with other answers?

I will give my insight later.

I know, right? That's what I can't understand.
-

This.
EDIT: my father is an engineer and made him solve it and said it was 52, and his method is completely logic, what the hell is going on here :lol
-
Oh wait, I see it now. 96 also works.
I'd love to know how he got 52 though. :lol
-
Ah okay, I was wrong about there only being one possible valid answer. Mine is the simplest of the two. BlobVanDam explained the harder one to me.
So since I'm a female and you dont' get to see this happen too often I'm sure:
I was wrong. Sort of. I mean, I was right but there was also another way to be right.
ok that's actually probably exactly how you're all used to seeing females admit wrongness. never mind. Carry on.
-
Ok now I can see how to get 96, fuck :rollin
-
Got 96 now also. A little trickier.
-
96 is the one I got as well.
-
Ok. There is two answers, the obvious one being 40:
1 + 4 = 5
2 + 5 = 12
3 + 6 = 21
8 + 11 = 40
Now, the catch is, the problem suggests you need to feel the void between 3+6 though 8+11.
1 + 4 = 5
2 + 5 = 12
3 + 6 = 21
4 + 7 = 32
5 + 8 = 45
6 + 9 = 60
7 + 10 = 77
8 + 11 = 96
So, the real problem is, there is actually two right answers or just one?
Personally, i think 96 is the only right answer.
-
That's not even how I came up with 96 as the alternate answer.

I see what you're getting at but as it's laid out in the OP I would say that the - or at least *A* - correct answer is 40 because the rule is "add the sum of the previous line to the current line" and AS LAID OUT (which I made a point to say in one of my early responses ;) ) the answer would be 40.
-
Well, technically they're both wrong, of course. But following the logic of this 'puzzle', I think 40 and 96 are both equally correct, whatever that means.
my father is an engineer and made him solve it and said it was 52
I'd love to know how
-
Yeah, I see no catch. You wouldn't assume it's incomplete, you assume the given problem is the entire pattern to solve. And from the given information, 40 and 96 are both equally valid imo.
-

You can do 8 x 11 (which is 88) + the first number (which is 8) = 96. It works too.

yes, what he said.

That's how I did it. Both answers work without extrapolation of additional data.

I'm more interested in how to get 52.

This.

Yeah, but i think the closest to the right answer is 96. I can be wrong and both be valid too.
Actually, i made the thread to see what you guys think, because there's no definitive solution to which is right.

My vote is for both 40 and 96 being equally valid, since I don't agree with your initial extrapolation (and strictly speaking both are equally incorrect anyway as standard equations). But then again, 96 is a self contained equation that only uses the information to figure out the trick. Depends on how you want to view the problem.
And I'd still love to hear if 52 holds up as a valid answer, or whether that's just plain wrong. :lol
-

Because you are grumpy.
(and strictly speaking both are equally incorrect anyway as standard equations).
See? Grumpy, no fun allowed :P :P :P
-
I went right to the 96 solution (using the first number x second number + first number pattern), but the logic behind 40 makes sense as well. Also curious to see the path to 52 :lol
-
I see these types of things on facebook a lot, and I hate them. They're always prefaced with something akin to, "Only geniuses will be able to solve this!!!"
The "correct" answer is usually very obvious. I actually have more fun trying to find out how some people got a "wrong" answer.
That being said, I got 96 initially and 40 soon after.
Here's a way to get 52:
Say the format is 'x + y = z'.
z = y*n + x, where the equation is nth in the list.
-
Basically this:
1 + (1)*4 = 5
2 + (2)*5 = 12
3 + (3)*6 = 21
8 + (4)*11 = 52
He saw the pattern in the parenthesis and thought that was it, and didn't think it had to do with the first term of each expression.
-
But, going by that logic (the number under the parenthesis is always the same as the first number), it's supposed to be:
8 + (8)*11 = 96
-
Once you blow out the idea that the equations themselves aren't really "equations" (in no base ten math scenario is "2+5=12") you kind of have free reign. I was the first to vote (though I didn't post) and immediately said "more than one answer".
There's the aforementioned 40, 96, and 52, but, once you start making assumptions and adding in variables (as with the "n" to get to 52) you can go basically anywhere. There is rationale for 32 and there is another, different, rationale for 96 as well.
Now here's an EASY question for you: what's the most logical equation BEFORE "1+4=5"?
-
But, going by that logic (the number under the parenthesis is always the same as the first number), it's supposed to be:
8 + (8)*11 = 96
But that's not the logic. The logic is it's the 4th equation in the series.
-
For you. My logic works too.
Now here's an EASY question for you: what's the most logical equation BEFORE "1+4=5"?
0 + 3 = 0 (of course, in the way the equations works in this sole problem)
Or i am dumb :sad:
-

No, that's pretty much it; and interestingly, it is the "precursor" equation in most of the other outcomes we've come up with as well; which bodes well for (but doesn't outright prove) their legitimacy.
-
You can also answer: 8+11 = 19 :hat :hat :hat
:lol
-
I got 96, but I agree that 40 is also an answer. I'm not sure I agree with the 52 solution, although the 8 + 11 is indeed the 4th equation.
(in no base ten math scenario is "2+5=12")
It is if you do it in the integer ring of modulu 5. That's technically still base 10, right?
-
Unsurprisingly, after reading all of the discussion, I arrived at an answer of "fuck this".
-
Also, this isn't math, it's deductive reasoning. Because we are operating outside the bounds of basic mathematics (the equations obliterate the possibility of basic arithmetic being the foundation of the puzzle), the mathematical principle of one correct answer is tossed out the window. Mathematics are used in calculating each equation, but logic must first be used to deduce a pattern before applying arithmetic principles to discovering the answer.
-
Yes this has less to do with actual mathematics and more about seeing patterns.
-
God, you guys are such nerds.
-
:angry: 4Q
-
Actually, that was for Hyperflex only :-*
Yeah, it's more about the patterns.
-
:angry: Oh
-
I got 96.

Hey if you're going to call somebody out over something, at least have the common decency to spell his name correctly.

That puzzle is indeed most Perflexing.

There'll be a SaCULL on them. :getoffmylawn:

The Saculling of the puns?
DAMN KOTOW

Talking about it...
Only i think my nickname is stupid? The one i actually wanted was already taken...
-
I wanted TwimpyFlazzo but like Liam Neeson's daughter - it was taken :emo:
-
I went with 40 (without scrolling down)
-
I didn't understand it at first as mathematically it didn't make any sense.
Then when I saw the answers I then went back and tried to work it out for myself.
-
Hm, it occults that you have to add up the result of the last equation.
To make sense:
1 + 4 = 5
2 + 5 + ? = 12
3 + 6 + ? = 21
8 + 11 + ? = ?
-
My first thought was 40. 96 is also great. I'll even give credit to 52 as well.
But these problems always rub me the wrong way because they are deliberately ambiguous to get people in Facebook comments arguing and to get more shares/likes. :lol

" Isn't God Amazing ? "
:rollin
-
So has anyone figured out if 40 is the only solution?
-
I got 96, not sure how you guys got 40.
-
They did 8 + 11 + 21.
-
Yeah, it took around 30 seconds but I just figured it out. :lol

96 was my first guess, going with a + b = a * (b + 1), but 40 works as well.
At least it isn't the argument about implied division again. :lol
-
96 was my first guess, going with a + b = a * (b + 1), but 40 works as well.
Yeah, that's what I did too.
-
96 was my first guess, going with a + b = a * (b + 1), but 40 works as well.
Wow, totally didn't see this pattern. Once I saw the pattern that gave 40 as the result, I couldn't see anything else.
-

I also did this one instantly, at first I didn`t get at all how people got 40 (I see it now).
