2. 259
3. 603
4. 83
5. None of the above/More than one of the above

Answer 1

Correct Answer - Option 2 : 259

Considering the given series

51, 52, 56, 83, 99, 224, 259, 603

The logic of the given series can be explained as

51 + 1³ = 52

52 + 2² = 56

56 + 3³ = 83

83 + 4² = 99

99 + 5³ = 224

224 + 6² = 260

260 + 7³ = 603

∴ Wrong term in given number series is 259
