Find the sum of first 22 terms of an AP in which d=l and 22nd term is 149.

Explanation

To find the sum of the first 22 terms of an arithmetic progression (AP) where the common difference \( d = 7 \) and the 22nd term is \( 149 \), we can follow these steps:

### Step 1: Identify the formula for the nth term of an AP
The nth term of an AP can be expressed as:
\[ T_n = a + (n - 1) \cdot d \]
where \( a \) is the first term, \( d \) is the common difference, and \( n \) is the term number.
