The sum of an infinite G.P. is 57 and the sum of their cubes is `9457 ,` find the G.P.

Explanation

To solve the problem, we need to find the terms of an infinite geometric progression (G.P.) given that the sum of the infinite G.P. is 57 and the sum of their cubes is 9457.

### Step 1: Set Up the Equations
Let the first term of the G.P. be \( A \) and the common ratio be \( r \).

The formula for the sum of an infinite G.P. is given by:
\[
S = \frac{A}{1 - r}
