Exercise 76 Page 139

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

Arithmetic

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 ratios are not the same. However, the differences are the same. Therefore, the sequence is an arithmetic sequence with a common difference of 5.
