What makes a sequence an arithmetic sequence?

Type of Sequence: Arithmetic sequence.
Common Difference: 9

Practice makes perfect
When a sequence is arithmetic, the difference between two consecutive terms is constant. By examining our sequence we can see that this is the case.

11 + 9 âź¶ 20 + 9 âź¶ 29 + 9 âź¶ 38 + 9 âź¶ ... Therefore, the sequence is an arithmetic sequence with common difference 9.
