Find the sum of first 24 terms of the list of numbers whose nth term is given by `a_n=3+2n`

Explanation

To find the sum of the first 24 terms of the sequence defined by the nth term \( a_n = 3 + 2n \), we can follow these steps:

### Step 1: Identify the first term and common difference
The first term \( a_1 \) can be calculated by substituting \( n = 1 \) into the formula:
\[ a_1 = 3 + 2(1) = 3 + 2 = 5 \]
