The image shows a 3x3 grid with some numbers, and one missing value indicated by a question mark. The numbers are as follows:

```
35  | 12 | 17
42  | 23 | 14
19  | 43 | ?
```

To determine the missing number, we need to find a pattern within the rows or columns.

Looking at the first two rows:

1. **Row 1 (35, 12, 17)**: The sum is \(35 + 12 + 17 = 64\).
2. **Row 2 (42, 23, 14)**: The sum is \(42 + 23 + 14 = 79\).

Next, look at the partial third row:

- The sum of the two known numbers is \(19 + 43 = 62\).

It appears that the sum of each row may follow a pattern. The difference between the sums of the first and second rows is 15 (\(79 - 64 = 15\)).

To follow this progression, we could expect the sum of the third row to be 94, since the difference of 15 is being added. Therefore, the missing number \(x\) should satisfy:

\[
19 + 43 + x = 94
\]

Solving for \(x\):

\[
62 + x = 94
\]

\[
x = 94 - 62 = 32
\]

Thus, the missing number is **32**.

Here are five related questions to consider:
1. What would happen if the row sums followed a different pattern?
2. Can you find a column-based pattern?
3. Is there a multiplicative pattern between the rows?
4. How would the solution change if the grid was 4x4?
5. Could diagonal sums reveal any additional patterns?

**Tip:** Always check multiple ways (rows, columns, diagonals) to find patterns when solving number grids.

What is the missing number in the grid: 35, 12, 17; 42, 23, 14; 19, 43, ?
