Lesson: Finding the 𝑛th Term of a Geometric Sequence Mathematics • Second Year of Secondary School

In this lesson, we will learn how to write explicit and recursive formulas for geometric sequences to find the value of the 𝑛th term in a geometric sequence and how to find a term’s order given its value.

Lesson Plan

Students will be able to

find the recursive rule for a geometric sequence,
find the number of terms in a given geometric sequence,
find the term rule for a geometric sequence,
use the recursive rule or the term rule to find the value of a numbered term in a geometric sequence,
use the recursive rule or the term rule to find a term’s order in a geometric sequence when given its value.
