Find the Missing Number…

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!
