determine if the sequence below is arithmetic or geometric indeterminate the common difference/ratio and simplest form 17, 13, 9

It is an arithmetic sequence

Common difference is -4

Step-by-step explanation:

Here, we want to determine the type of sequence

As we can see, the difference between each of the terms is as follows;

13-17 = 9-13 = -4

What this mean is that we have a constant common difference

This simply shows that the sequence we have is an arithmetic sequence

The common difference is thus;

13-17 = 9-13 = -4
