# Lesson Plan: Representing Sequences Mathematics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to represent a sequence as a function of a positive integer variable called an index (𝑛).

#### Objectives

Students will be able to

- write an expression for the term of a given geometric or arithmetic sequence,
- write an expression for the term of a given arithmetic sequence when given any numbered term and the common ratio,
- write an expression for the term of a geometric sequence when given any numbered term and the common ratio,
- find any numbered term of a sequence when given an expression for the term,
- write out a sequence when given an expression for the term.

#### Prerequisites

Students should already be familiar with

- arithmetic sequences,
- geometric sequences.

#### Exclusions

Students will not cover

- questions not involving the term of a sequence.
