Find out the wrong number in the given sequence of numbers.

4.

1, 8, 27, 64, 124, 216, 343

 [A]. 8 [B]. 27 [C]. 64 [D]. 124

Explanation:

The numbers are 13, 23, 33, 43 etc. So, 124 is wrong; it must have been 53 i.e., 125.

 Anonymous said: (Jun 26, 2017) Is it correct if we see it this way? 1-odd. 8-even. 27-odd. 64-even. 124-even. 216-even. 343-odd. So there should be an odd number between 64 and 216 to maintain the odd-even series hence 124 is wrong.
