Exercise 14 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 subtract 30. Therefore, the common difference of the sequence is - 30. 60+( - 30) ⟶30+( - 30) ⟶0+( - 30) ⟶-30 To find the next three terms in the sequence, we will extend this pattern three times. 60& +( - 30) ⟶30+( - 30) ⟶0+( - 30) ⟶-30 ... & +( - 30) ⟶ -60 +( - 30) ⟶ -90 +( - 30) ⟶ -120 Therefore, the next three terms are - 60, - 90, and - 120.
