Is the sequence defined by ` a_(n) = 3n^(2) + 2 an ` A.P. ?

Explanation

To determine if the sequence defined by \( a_n = 3n^2 + 2 \) is an arithmetic progression (A.P.), we need to check if the common difference between consecutive terms is constant.

### Step-by-Step Solution:

1. **Identify the Sequence**:
The sequence is given by the formula \( a_n = 3n^2 + 2 \).

2. **Calculate the First Few Terms**:
