Exercise 9 Page 204

What is the change between pairs of consecutive terms?

-1.5

Practice makes perfect

By observing the change that occurs between consecutive terms, we can determine the common difference of the arithmetic sequence. Here, we can see that each term is 1.5 less than the previous term.

6.5+( - 1.5) ⟶5+( - 1.5) ⟶3.5+( - 1.5) ⟶2+( - 1.5) ⟶... Therefore, the common difference is - 1.5.
