Answer 1

130 is the answer of the question

Answer 2

(C) 132.

Given:

8,15,34,71........... ???

To find:

Next number in series

Solution:

It can be seen that these numbers are cubes of natural number starting from 1 and then add 7 to each cube.

8 -7 = 1 = 1³

15 - 7 = 8 = 2³

34 - 7 = 27=3³

71 - 7 = 64 = 4³

So, now we have to find cube of 5 and add 7 to the cube

5³ + 7 = 125+7 = 132

Hence, the next number in series is 132.
