Find the common difference for the terms of the arithmetic sequence: 11, 23, 35, 47, 59,

The common difference is 12. However, let’s take a look at how we got there!

First take the 2nd term (23) and find the difference from the 1st term (11). The difference is 12.

Repeat this for the remaining terms ...

35 - 23 = 12

47 - 35 = 12

59 - 47 = 12

The common difference is 12.
