Lesson 3 Summary

Two types of sequences were studied:

Arithmetic Sequence: A sequence is called arithmetic if there is a real number d such that each term in the sequence is the sum of the previous term and d.

Geometric Sequence: A sequence is called geometric if there is a real number r such that each term in the sequence is a product of the previous term and r.

In this lesson, students review the basic concept of an arithmetic sequence before then extending these ideas to geometric sequences. A variety of application problems are emphasized.
