Question

In each of the following number series, the wrong number is given, find out that number.

5541, 5506, 5425, 5304, 5135, 4910, 4621

1. 5541
2. 5506
3. 5425
4. 4621
5. 4910

Answer 1

Correct Answer - Option 1 : 5541

The logic of the given series can be explained as;

5531 – 5506 = 25 = 5² (5541 is written at place of 5531)

5555 – 5506 = 49 = 72

5506 – 5425 = 81 = 9²

5425 – 5304 = 121 = 11²

5304 – 5135 = 169 = 13²

5135 – 4910 = 225 = 15²

4910 – 4621 = 289 = 17²

∴ Wrong term in given number series is 5541.
