3311 - Math test


I'm only posting this because I figured it out right away. Everything is not as it looks. Yes there is a trick. That's the test. To figure out the trick. This is another one of those puzzles that once you know what it is it looks easy.

40?

My thought too.

So then I forgot to put the answer in the comments last night. 40 is right for normal people. The math geeks came up with several other answers.

And in case non math people don't get it, the trick is adding the previous answer to the obvious answer. I.E. 3+6=9+12=21

Interesting.
I solved it as:
1 + 4 = 1 x 4 (+1) = 5
2 + 5 = 2 x 5 (+2) = 12
3 + 6 = 3 x 6 (+3) = 21
so...
8 + 11 = 8 x 11 (+8) = 96

John - That's just one of the other more complicated answers I saw. There are other ways to get to 96.
