Question

Choose the number (X) that should come next in this series (1 4 9 16 X)

Answer 1

25

Explanation:

The difference between 4 and 1 is 3.

The difference between 9 and 3 is 5.

The difference between 16 and 9 is 7.

So the difference between the next number and 16 should be the next odd number which is 9

25 - 16 = 9
