The sum of a geometric series is 14 and the series of cubes of its terms has sum 392. Find the series.

Arin Mishra 25th Dec, 2019

Hello,

Let the Series be:

a, ar, ar^2 ... so the sum will be:

a/1-r=14......(1)

now we cubed the series so terms become:

a^3, (ar)^3, (ar^2)^3... So the sum of this series will be

a^3/1-r^3=392......(2)

Solve (1) and (2) to get the answer.

Hope this Helps,

All the Best.
