Find the second term and nth term of an A.P. whose 6th term is 12 and the 8th term is 22.

Explanation

To find the second term and the nth term of an arithmetic progression (A.P.) whose 6th term is 12 and the 8th term is 22, we can follow these steps:

### Step 1: Define the terms of the A.P.
Let the first term of the A.P. be \( a \) and the common difference be \( d \).

### Step 2: Write the expressions for the 6th and 8th terms.
The nth term of an A.P. is given by the formula:
\[
