Number Pyramid Puzzle: Replace the question mark in 13 seconds

Solution:

Here is the step-by-step logic behind the solution:

If you read the logs in each row from left to right as a single multi-digit number, a pattern of multiplying by 8 emerges:

• Row 1: 9

• Row 2: 72 (9 × 8 = 72)

• Row 3: 576 (72 × 8 = 576)

Following this exact pattern, multiply the third row’s number by 8 to find the value for the fourth row:

• Row 4: 576 × 8 = 4608

The blocks on the bottom row display 4, 6, ?, 8. Matching this to 4608 reveals that the missing digit is 0.

Correct Answer: The missing number is 0.
