What is the change between pairs of consecutive terms?
16 and - 32
Practice makes perfect
By observing the change that occurs between each consecutive term, we can describe the pattern of the sequence. Here, we see that the common ratio from one term to the next is - 2.
1* (- 2) ⟶- 2* (- 2) ⟶4* (- 2) ⟶- 8
To find the next two terms in the sequence, we will extend this pattern twice.
1* (- 2) ⟶- 2* (- 2) ⟶4* (- 2) ⟶- 8* (- 2) ⟶16* (- 2) ⟶- 32
