What number should replace the question mark inside the triangle?
Correct answer: 12
Explanation:
Look at the numbers around each triangle.
The rule is: multiply the two bottom numbers, then subtract the top number.
First triangle: 3 × 3 - 6 = 9 - 6 = 3
Second triangle: 3 × 1 - 2 = 3 - 2 = 1
Third triangle: 4 × 3 - 9 = 12 - 9 = 3
So for the missing triangle:
4 × 5 - 8 = 20 - 8 = 12
Therefore, the missing number is 12.
Finall answer to this puzzle: 12
