Determine whether the following sequence is geometric. if so, find the common ratio. 3, 15, 75, 375

This sequence is geometric and the common ratio is 5.
You can tell that it is not arithmetic because there is not a common difference between each number (75-15=60, 15-3=12). You can find the common difference by dividing any term by the term that case before it. So for example 15/3=5 or 75/15=5.

Hope this helps!

The linear equation is: y=ax+b
