In the provided image, a 3x3 grid of numbers is displayed, with one of the squares containing a question mark (?). The grid looks like this:

\[
\begin{matrix}
10 & 14 & 6 \\
15 & ? & 8 \\
5 & 9 & 16
\end{matrix}
\]

We need to determine the value of the missing number (represented by the "?").

### Analysis:
The numbers surrounding the question mark (central position) seem to follow a logical pattern or sequence. Possible strategies include:
1. **Row-wise or column-wise arithmetic patterns.**
2. **Considering a magic square structure (where the sums of numbers in rows, columns, and diagonals are equal).**

### Approach:
- Let’s start by adding the rows:
    - First row: \(10 + 14 + 6 = 30\)
    - Third row: \(5 + 9 + 16 = 30\)
    - This suggests that the second row should also sum to 30. Thus:
    \[
    15 + ? + 8 = 30
    \]
    Simplifying this:
    \[
    15 + ? + 8 = 30 \implies ? = 30 - (15 + 8) = 30 - 23 = 7
    \]
Thus, the missing number is \( \boxed{7} \).

In a 3x3 grid of numbers, one number is missing in the center position, represented by a question mark (?). The grid looks like this: [ [10, 14, 6], [15, ?, 8], [5, 9, 16] ]. Determine the missing number.

In this problem, we explore how to solve a 3x3 grid number puzzle by identifying arithmetic patterns. Given the grid [ [10, 14, 6], [15, ?, 8], [5, 9, 16] ], the goal is to find the missing number using row sums. This problem is suitable for students in Grades 6-8.
