Decision No. 1 To the sum of each equation must be added to the sum of the previous. So

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

21 + 8 + 11 = 40

Thus, one of the correct answers 40.

Solution # 2 Another pattern can be observed if we use the formula a + b = a + a(b):

1 + (4×1) = 5
2 + (5×2) = 12
3 + (6×3) = 21

Total: 8 + (8×11) = 96

Most people give the second answer. And what happened to you?
