Let's solve the arithmetic sequence problem step by step.

Given:
- First term (**a**) = 5
- Common difference (**d**) = 2
- Number of terms (**n**) = 15

The sum of the first **n** terms of an arithmetic sequence is given by:
$$ S_n = \frac{n}{2} [2a + (n-1)d] $$

Plug in the values:
$$
S_{15} = \frac{15}{2} [2 \times 5 + (15-1) \times 2]
$$
$$
= \frac{15}{2} [10 + 28]
$$
$$
= \frac{15}{2} \times 38
$$
$$
= 15 \times 19
$$
$$
= 285
$$

**Final Answer:**  
**285** (Select this option)
