Find the sum of the following APs : (i) 2, 7, 12, . . . , to 10 terms.

Explanation

To find the sum of the first 10 terms of the arithmetic progression (AP) given by 2, 7, 12, ..., we can follow these steps:

### Step-by-Step Solution:

**Step 1: Identify the first term (A) and the common difference (D) of the AP.**
- The first term \( A \) is the first number in the sequence, which is \( 2 \).
- The common difference \( D \) can be calculated by subtracting the first term from the second term:
\[
