Find the `20^(t h)`and `n^(t h)`terms of the G.P. `5/2`,`5/4`,`5/8,dotdotdot`

Explanation

To find the 20th and nth terms of the geometric progression (G.P.) given by the sequence \( \frac{5}{2}, \frac{5}{4}, \frac{5}{8}, \ldots \), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the First Term (a)**:
The first term \( a \) of the G.P. is given as:
\[
a = \frac{5}{2}
