I think I got it π

Sorry, 40!
96 2ez

8+11=19. Why do I care that the person that did the first three were dumb?
The first one is legit. It's just the 2nd and 3rd that get wonky.

gonna say 96 (8 + (8 x 11)).
I mean I could be wrong, but that is way over complicating what is going on. The second eqation is its sum plus previous answer (7 + 5). Third is its sum plus previous (9 + 12). So forth is sum plus previous (19 + 21). Nothing accumulative.
52
40?
Sum of previous answer/row plus new two numbers
1st iteration is A+(1*B)
2nd is A+(2*B)
3rd is A+(3*B)
Etc
So its iteration# * B for each
However....
Now I see that A is the iteration, and 8 is not 4. So the answer should have been 96.

Basic pattern recognition.
It seems both 40 and 96 are potential ... (though technically, the answer is 19).
I haven't seen (or figured) the explanation for 52 yet.

It's 40.
Nope. I'm not a genius 40
