Did you get it right?
This number pattern asks you to continue the sequence 2, 5, 11, 23.

The Answer
The correct answer is: 47.
Here is why
- Each number is doubled, then 1 is added.
- 2 x 2 + 1 = 5.
- 5 x 2 + 1 = 11.
- 11 x 2 + 1 = 23.
- 23 x 2 + 1 = 47.
Why people miss it
The jump between numbers grows, so the pattern can look random until you test doubling plus one.
