1 + 4 = 5
2 + 5 = 12
3 + 6 = 21
8 + 11 = ?
Answer 40
There are two correct ways to solve this question. The first is to add the equation, then combine the sum to that of the previous equation, giving you a final total of 40, after you add 21 to 8 + 11. The second solution involves multiplying the second number of the equation by the number you are adding to it, which gives you a harder-to-find correct answer of 96.
