## 11-1 Geometric Sequences

**Objectives**: Recognize and extend geometric sequences & find the nth term of a geometric sequence.

In a

To find the common ratio, r, divide any term by the previous term in the sequence.

**geometric sequence**, there is a**common ratio**between each term. (In a previous lesson, we learned an arithmetic sequence has a common difference. Please note the difference.)To find the common ratio, r, divide any term by the previous term in the sequence.
