Question

Wrong Number in the Series 1, 8, 27, 124, 216, 343
Find out wrong number 1, 8, 27, 124, 216, 343?

Answer 1

When you look at the given series 1, 8, 27, 124, 216, 343, you can very quickly make a distinct observation. We have cubes of numbers 1,2, 3, 6 and 7. There is only one number which is not a perfect cube of a number.

So the wrong number in this series is 124. (Had it been 125, we would have got a good series)
