The question is:
9 = 90
8 = 72
7 = 56
6 = 42
3 =?
It seems like a simple equation, using basic math we learned early on. But there’s more to it.
ANSWER
Each result is calculated as n×(n + 1).
Let’s check:
For 9: 9×10 = 90
For 8: 8×9 = 72
For 7: 7×8 = 56
For 6: 6×7 = 42
For 3: 3×4 = 12
So the missing number is 12.
