The sum of first three terms of a G.P. is 13/12 and their product is -1. Find the G.P.

Explanation

To solve the problem, we need to find the first three terms of a geometric progression (G.P.) given that their sum is \( \frac{13}{12} \) and their product is \( -1 \).

### Step-by-step Solution:

1. **Assume the terms of the G.P.**:
Let the first term be \( a \) and the common ratio be \( r \). The first three terms can be expressed as:
\[
\frac{a}{r}, \quad a, \quad ar
