Geometric Sequences

 

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.
