The first and the last terms of an A.P. are `a\ a n d\ l` respectively. Show that the sum of nth term from the beginning and nth term from the end is `a+ldot`

Explanation

To show that the sum of the nth term from the beginning and the nth term from the end of an Arithmetic Progression (A.P.) is equal to \( a + l \) (where \( a \) is the first term and \( l \) is the last term), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the nth term from the beginning**:
The nth term of an A.P. can be calculated using the formula:
\[
a_n = a + (n - 1)d
