The first term of a G.P. is 1. The sum of the third term and fifth term is 90. Find the common ratio of G.P.

Explanation

To solve the problem step by step, we will follow the logic presented in the video transcript.

### Step 1: Identify the first term and the common ratio
We know that the first term \( A \) of the geometric progression (G.P.) is given as:
\[ A = 1 \]
Let the common ratio be \( R \).

### Step 2: Write the expressions for the third and fifth terms
