Select the number from among the given options that will come next in the following series:
​6, 25, 62, ?​​

Given:  6, 25, 62, ?

Logic:  (consecutive natural number)³ - 2 = next number 

2³- 2 = 8 - 2 = 6

3³ - 2 = 27 - 2 = 25

4³- 2 = 64 - 2 = 62

So, next number is:

5³- 2 =125-2 = 123 

Thus, correct option is (a).
