In the following number series, one number is wrong. Find the wrong number: 3, 13, 33, 137, 681, 4090.
- 33
- 681
- 4090
- 137
Correct answer: 4090
Solution
The series follows a pattern where each term is obtained from the previous term by a fixed operation, but one term breaks that pattern. On checking the progression, 4090 does not fit the intended sequence, so it is the wrong number.
