Here’s a 3×3 number puzzle. Eight squares are filled, and one is empty, marked with a question mark. Can you figure out what goes there?

The grid is:
Row 1: 1, 2, 3
Row 2: 2, 4, 6
Row 3: 3, 6, ?
Notice the pattern:
- Row 1 follows multiples of 1: 1, 2, 3
- Row 2 follows multiples of 2: 2, 4, 6
- Row 3 follows multiples of 3: 3, 6, 9
So, the missing number is 9! The numbers fit neatly into their multiplication tables. You’ve cracked it!
