Exercise 81 Page 139

Calculate the difference and ratio between consecutive terms. Is either of these the same throughout the sequence?

Geometric

Practice makes perfect

We want to identify the given sequence as arithmetic, geometric, or neither. To do so we will calculate the difference and ratio between consecutive terms.

We can see above that the differences are not the same. However, the ratios are the same. Therefore, the sequence is geometric with a common ratio of - 12.
