Determine the AP whose `3^(r d)`term is 5 and the `7^(t h)`term is 9.

Explanation

To determine the arithmetic progression (AP) whose 3rd term is 5 and whose 7th term is 9, we can follow these steps:

### Step 1: Understand the formula for the nth term of an AP
The nth term of an arithmetic progression can be expressed as:
\[ T_n = A + (n - 1)d \]
where:
- \( A \) is the first term,
- \( d \) is the common difference,
