Holy shite, some of you can't add two numbers.

True, this will only work when b = a + 3 for every line. It makes the value of b irrelevant.

it is 96.
1 * 4 + 1 = 5
2 * 5 + 2 = 12
3 * 6 + 3 = 21
8 * 11 + 8 = 96
1 * 4 + 1 = 5
2 * 5 + 2 = 12
3 * 6 + 3 = 21
8 * 11 + 8 = 96

Possible answers:
1) You add each equation to the previous result, so
1 + 4 = 5
2 + 5 = 7 + 5 = 12
3 + 6 = 9 + 12 = 21
8 + 11 = 19 + 21 = 40
or
2) You apply the pattern of both numbers increasing by 1 and the equations progressing in sequential order and extrapolate out to what it would be when you got to the last one, so
1 + 4 = 5
2 + 5 = 7 + 5 = 12
3 + 6 = 9 + 12 = 21
4 + 7 = 11 + 21 = 32
5 + 8 = 13 + 32 = 45
6 + 9 = 15 + 45 = 60
7 + 10 = 17 + 60 = 77
8 + 11 = 19 + 77 = 96
ETA: or, apply the formula (a*b)+a=X, so
(8 * 11) + 8 = 96
As others note, (a * b) + a = a * (b + 1), so
8 * (11 + 1) = 96

You left out the possibility that the answer to each line is independent of the others. That's how you can get 96 without extrapolating anything.
A x (B + 1) = C
A x (B + 1) = C

True.

8+11=19

8th grade math teachers to teach students to only work with what is given in a problem, not be confused by information that may lead to assertions that have nothing to do what is being asked in the problem.

96
1st number times 2nd number, then add first number to the result
8x11=88+8=96
i showed my work. do i get points even if wrong?

the only answer is to deactivate facebook

there are three possible solutions that would be correct depending what pattern you use.
I think it's 40 as that is the most straightforward pattern.

definitely 96

The original provider of the problem states that only 1 person in 1000 will get the correct answer, yet based on this thread and Facebook it seems 999 people out of 1000 will produce 40 or 96.

I'm sure this has been discussed already, but doesn't it depends on what the question is asking? If it's stating that "8+11" is the next in the sequence, then the answer is different than if it's asking "keep going until you get to '8+11' and what is that answer?"
Also, there are two ways to get to 96. the shortcut way is "the two numbers multiplied together plus the first number."
4 x 1 = 4 + 1 = 5
2 x 5 = 10 + 2 = 12
3 x 6 = 18 + 3 = 21
8 x 11 = 88 + 8 = 96
The second way is "add the two numbers together then add the previous total."
1 + 4 = 5
2 + 5 = 7 + 5 = 12
3 + 6 = 9 + 12 = 21
4 + 7 = 11 = 21 = 32
5 + 8 = 13 + 32 = 45
6 + 9 = 15 + 45 = 60
7 + 10 = 17 + 60 = 77
8 + 11 = 19 + 77 = 96
