Lesson: Geometric Sequences Mathematics • Second Year of Secondary School

Join Nagwa Classes

Attend live General Mathematics sessions on Nagwa Classes to learn more about this topic from an expert teacher!

In this lesson, we will learn how to calculate the common ratio, find next terms in a geometric sequence, and check if the sequence increases or decreases.

Lesson Plan

Students will be able to

understand that the ratio of two successive terms of a geometric sequence is constant and is called the common ratio,
identify the common ratio of a geometric sequence from its recursive formula,
find the first terms of a geometric sequence using the common ratio,
identify whether a given sequence is geometric,
classify a given geometric sequence as decreasing or increasing,
identify the graphical representation of the geometric sequence.
