Exercise 20 Page 542

What is the change between pairs of consecutive terms?

1/9

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 dividing by 3. 81÷ 3 →27÷ 3 →9÷ 3 →3÷ 3 →1... To find the seventh term in the sequence, we will extend this pattern twice. 81÷ 3 →27÷ 3 →9÷ 3 →3÷ 3 →1÷ 3 → 13÷ 3 → 19
