The question asks to find the missing number in a 3x3 grid where some numbers are given, and we need to replace the '?' with the correct number from the options provided: 8, 10, 12, or 14.

Here is the grid:

\[
\begin{bmatrix}
4 & 9 & 20 \\
8 & 5 & 14 \\
10 & 3 & ? \\
\end{bmatrix}
\]

We need to find a pattern that fits the relationship between the numbers in each row or column.

### Observing Rows:
- First row: \( 4 + 9 = 13 \), \( 13 + 7 = 20 \)
- Second row: \( 8 + 5 = 13 \), \( 13 + 1 = 14 \)
- Third row: \( 10 + 3 = 13 \), so \( 13 + ? = \), the missing number must be **13 + 1 = 14**.

Thus, the missing number is 14.

The correct answer is **D) 14**.

**Tip:** Always verify whether the patterns hold consistently across rows and columns for added confidence in your solution.

Consider the square: 

 4  9  20 
 8  5  14 
 10 3  ? 

Which number should replace '?' in the square? (Options: A) 8, B) 10, C) 12, D) 14)
