Students learn how to work out the nth term of a geometric progression in the form arn-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.
