Question
The image displays an arithmetic sequence problem, asking to find the partial sum \( S_{16} \) for the sequence where the first term \( a = 7 \) and the common difference \( d = 7 \).

The sequence is defined as:
\[ a_n = a + (n-1)d \]

To find the partial sum \( S_{n} \), use the formula:
\[ S_{n} = \frac{n}{2} \times (2a + (n-1)d) \]

Given:
- \( a = 7 \)
- \( d = 7 \)
- \( n = 16 \)

Calculate \( S_{16} \) using these values in the formula.
