Find the next two terms of the arithmetic sequence 2,8

If it’s an arithmetic sequence, the terms are gonna change by a common value (meaning that the difference between consecutive terms is the same). in this case, in order to get from 2 to 8, you add 6, so the third term would be 8+6 which is 14, and the fourth term would be 14+6 which is 20.

so the arithmetic sequence would look like this:
2, 8, 14, 20

hope this helps

17 is c. congruent means equal in size
