Answer: What Number Is Missing in the Circle Puzzle?

Did you get it right?

This number pattern shows three circles. Each circle has a top, left, right, and bottom number, and the last bottom number is missing.

Answer: What Number Is Missing in the Circle Puzzle?

The Answer

The correct answer is: 30.

Here is why

  1. In the first circle, the top number is 3. The left is 6, the right is 9, and the bottom is 18.
  2. That means the left is 2 times the top, the right is 3 times the top, and the bottom is 6 times the top.
  3. For the third circle, the top number is 5. So the missing bottom number is 5 x 6 = 30.

Why people miss it

The trick is to compare each position in the circle, not just read the numbers from left to right.
