Find The Math Pattern Like A Genius

The answer is 72.

The pattern is found by adding the two numbers together and then multiplying that sum by 3.

Here is the pattern applied to each row:

• 1 + 5 = 18: (1 + 5) = 6 ⇒ 6 × 3 = 18

• 2 + 7 = 27: (2 + 7) = 9 ⇒ 9 × 3 = 27

• 3 + 9 = 36: (3 + 9) = 12 ⇒ 12 × 3 = 36

• 5 + 10 = 45: (5 + 10) = 15 ⇒ 15 × 3 = 45

Following this exact rule for the final equation:

• 4 + 20 = ?: (4 + 20) = 24 ⇒ 24 × 3 = 72
