Answer 2

I hope you don't mind, but I've answered this several times in the past two weeks, so I'm just copying my previous answer from the last time this question was asked:

This is a common math problem. There are two ways to answer this question but both will give you the same answer. There is a misconception that this can also equal 40. If someone posts that the answer is 40, please let me know and I will explain why that is not actually the answer.

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

These equations are actually:

1*(4+1)=5
2*(5+1)=12
3*(6+1)=21
8*(11+1)=96

Therefore:
8+11 = 96
