To the sum of each equation should be added the sum of the previous one. so

4 + 1 = 5

5 + 2 + 5 = 12

12 + 3 + 6 = 21

21 + 8 + 11 = 40

Thus, one of the correct answers - 40.

Another pattern can be seen 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
