Answer:
6
Step-by-step explanation:
We can find the common difference by subtracting one number in the sequence from the one ahead of it.
27-21=6
21-15=6
15-9=6
9-3=6
The differences between each number is 6.
Because the difference is the same between each number in the sequence, that makes 6 the common difference.
