I'm more interested in how to get 52.

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.

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.

See? Grumpy, no fun allowed

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

Aefenwelg · « **Reply #41 on:** April 25, 2016, 08:00:50 AM »

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.

Sacul · « **Reply #42 on:** April 25, 2016, 08:03:11 AM »

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.

Outcrier · « **Reply #43 on:** April 25, 2016, 08:11:25 AM »

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

Stadler · « **Reply #44 on:** April 25, 2016, 08:12:30 AM »

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 that's not the logic. The logic is it's the 4th equation in the series.

For you. My logic works too.

0 + 3 = 0 (of course, in the way the equations works in this sole problem)

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.

Outcrier · « **Reply #48 on:** April 25, 2016, 08:27:27 AM »

You can also answer: 8+11 = 19

Onno · « **Reply #49 on:** April 25, 2016, 09:46:09 AM »

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.

Quote from: Stadler on April 25, 2016, 08:12:30 AM

(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?

Sir GuitarCozmo · « **Reply #50 on:** April 25, 2016, 11:26:49 AM »

Unsurprisingly, after reading all of the discussion, I arrived at an answer of "fuck this".

Hyperplex · « **Reply #51 on:** April 25, 2016, 12:22:37 PM »

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.

Kotowboy · « **Reply #52 on:** April 25, 2016, 12:29:41 PM »

Yes this has less to do with actual mathematics and more about seeing patterns.

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.

Outcrier · « **Reply #69 on:** April 25, 2016, 02:28:39 PM »

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 + ? = ?
