# Lesson Plan: Applications of Arithmetic Sequences Mathematics • 9th Grade

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to solve real-world applications of arithmetic sequences, where we will find the common difference, š¯‘›th term explicit formula, and order and value of a specific sequence term.

#### Objectives

Students will be able to

• model a real-world problem using arithmetic sequence,
• apply methods from arithmetic sequences to solve real-world problems,
• interpret tables and graphs that represent arithmetic sequences.

#### Prerequisites

Students should already be familiar with

• the common difference of an arithmetic sequence,
• the term formula for arithmetic sequence,
• the sum of terms in an arithmetic sequence.

#### Exclusions

Students will not cover

• geometric or other types of sequence.
