Throughout this mathematics lesson students learn how to derive the nth term for geometric sequences in the form ar^n-1.  As learning progresses they consider progressions with fraction and negative common ratios.

Differentiated Learning Objectives

• All students should be able to find the common ratio of a geometric sequence.
• Most students should be able to find the common ratio and nth term of a geometric sequence.
• Some students should be able to solve compound percentage problems using geometric sequences.
