Lesson: Finding the Arithmetic Sequence Mathematics

In this lesson, we will learn how to find arithmetic sequences given information about their terms and relationships between them.

Lesson Plan

Objectives

Students will be able to

  • find arithmetic sequences given information about two nonconsecutive terms,
  • find arithmetic sequences given equations relating their terms including sums and products,
  • solve problems related to arithmetic sequences given relations between their terms.

Prerequisites

Students should already be familiar with

  • working with arithmetic sequences including how to work out the common difference, find the general term, and find individual terms,
  • common formulas associated with arithmetic sequences, for example, 𝑇=𝑇+(𝑛−1)𝑑,
  • forming and solving systems of equations,
  • arithmetic mean.

Exclusions

Students will not cover

  • arithmetic series.
