Complete the series:

10, 14, 23, 39, 64, ? ​​

Given: 10, 14, 23, 39, 64, ? ​​

Logic: Numbers are increasing perfect square of natural number starting from 2.

10 + 4 = 14

14 + 9 = 23

23 + 16 = 39

39 + 25 = 64 

Next term is: 6²= 36

64 + 36 = 100

So, the missing term is 100.

Thus, correct option is (b).
