Geometric Progression: Overview

‘Geometric Progression’ is Chapter 20 of Class 11 Mathematics. In this chapter, students will learn about geometric progression, its types and formulas. A geometric progression is one of the special types of progression where the successive terms contain a constant ratio that is known as a common ratio. Geometric progression is also known as GP. The geometric progression is represented in the form of a, ar, ar2, ar3.... where a is represented as the first term and r is represented as the common ratio of the progression. The common ratio of the progression can have both positive as well as negative values. To find the values for a geometric series, students only need the first term and the constant ratio. A defined sequence of non-zero numbers is called a geometric progression if the ratio of a particular term and the term preceding it, is always a constant quantity.


In this Chapter, students shall learn more about the geometric progression formulas, and the different types of geometric progressions. Students will learn about the two types of geometric progressions which are based on the number of terms in the progression series. The two types of a geometric progression are the infinite geometric progression and the finite geometric progression. 

  • Finite Geometric Progression

Finite geometric progression is the type of geometric series that contains a finite number of terms. It is the type of geometric progression where the last term is defined. For example 1/2, 1/4, 1/8, ...,1/32768 is a finite geometric series where the last term is defined as 1/32768.


  • Infinite Geometric Progression

Infinite geometric progression is the type of geometric series that contains an infinite number of terms. It is the type of geometric progression where the last term is not defined. For example, 3, −6, +12, +... is an infinite series where the last term is not at all defined.


In RD Sharma Class 11 Chapter 20 - Geometric Progression exercise 20.1, students will learn different types of concepts like - The general term of a Geometric Progression, Selection of terms in Geometric Progression, Sum of the terms of a Geometric Progression, Sum of an Infinite Geometric Progression, Properties of geometric progressions,  Insertion of geometric means between two given numbers, Some important properties of geometric means.
