Explanation:

Let’s break it down row by row:

- First row: 50, 48, 30

If you notice: 50 - 48 = 2; 48 - 30 = 18 (no obvious pattern).

- Second row: 56, 32, 40

56 - 32 = 24; 32 - 40 = -8 (again, not matching the previous row’s differences).

Here's where it gets interesting—maybe it's column-wise:

- First column: 50, 56, 350

Second column: 48, 32, 192

Third column: 30, 40, ?

Let’s try this: look for a pattern involving multiplication or addition across columns.

Across Columns:

- 50 × 7 = 350 (First column)

- 48 × 4 = 192 (Second column)

So, if we keep the pattern:

- 30 × ? = Third row, third column

But 30 × 5 = 150

So the missing number is 150.

Option 1: 150

- The correct option is 1, 150.

- This fits the consistent “third row = first row × a whole number” across columns.

- The multipliers differ, but only one option (150) matches this multiplication logic for the third column.
