Exercise 13 Page 204

By observing the change that occurs between consecutive terms, we can describe the pattern of the arithmetic sequence. Here, we see that to get from a term to the next term we add 5. Therefore, the common difference of the sequence is 5.

16 + 5 ⟶ 21 + 5 ⟶ 26 + 5 ⟶ 31 To find the next three terms in the sequence, we will extend this pattern three times. 16+ 5 →21+ 5 →26+ 5 →31+ 5 → 36+ 5 → 41+ 5 → 46
