To find the pattern in the highlighted numbers, let's list them out and look for a rule.
Step 1: List the highlighted numbers.
Looking at the grid, the yellow boxes are on these numbers:
9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99.
Step 2: Check the difference between the numbers.
Let's see how much each number increases by:
* $18 - 9 = 9$
* $27 - 18 = 9$
* $36 - 27 = 9$
* $45 - 36 = 9$
The numbers go up by
9 each time. This means they are multiples of 9 (the 9 times table).
Step 3: Verify with multiplication.
Let's check if these numbers match the 9 times table:
* $9 \times 1 = 9$
* $9 \times 2 = 18$
* $9 \times 3 = 27$
* $9 \times 4 = 36$
* $9 \times 5 = 45$
* $9 \times 6 = 54$
* $9 \times 7 = 63$
* $9 \times 8 = 72$
* $9 \times 9 = 81$
* $9 \times 10 = 90$
* $9 \times 11 = 99$
All the highlighted numbers fit this pattern perfectly.
Final Answer: The highlighted numbers are the multiples of 9 (the 9 times table): 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, and 99.
