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.

The Answer
The correct answer is: 30.
Here is why
- In the first circle, the top number is 3. The left is 6, the right is 9, and the bottom is 18.
- That means the left is 2 times the top, the right is 3 times the top, and the bottom is 6 times the top.
- 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.
