The question is asking for the general term of an arithmetic sequence where the first term \( a_1 = 8 \) and the second term \( a_2 = 16 \).

### Step 1: Finding the common difference (\(d\))
In an arithmetic sequence, the common difference \(d\) is calculated as:
\[
d = a_2 - a_1 = 16 - 8 = 8
\]
So, the common difference is \(d = 8\).

### Step 2: General formula for an arithmetic sequence
The general term of an arithmetic sequence is given by:
\[
a_n = a_1 + (n - 1)d
\]
Substituting \(a_1 = 8\) and \(d = 8\):
\[
a_n = 8 + (n - 1) \cdot 8 = 8 + 8n - 8 = 8n
\]

Thus, the correct expression for the general term of the sequence is:
\[
a_n = 8n
\]

Looking at the answer choices:
- \( \text{A: } 4n - 2 \)
- \( \text{B: } 2n + 4 \)
- \( \text{C: } 2n + 2 \)
- \( \text{D: } 4n + 2 \)

None of these options exactly match \(a_n = 8n\), so there seems to be an error in the provided choices. However, based on the sequence structure, the correct general term is \(8n\).
