What is a Geometric Sequence or Geometric Progression?

Geometric Sequence is also referred to as Geometric Progression. It is defined as the list of numbers in which each term in the sequence is multiplied by a constant non zero number called the common ratio "r".

Example: 1, 3, 9, 27, 81, …

The above sequence is an example of Geometric Progression in which each term in the sequence is multiplied by the common ratio 3 with the previous number.

How to find the Sum of a Geometric Sequence?

After learning about how to find a geometric sequence of a finite number you must be curious about how to find the sum of their geometric sequence. It may seem a bit difficult for you but following certain tricks will help you find the value in quite simple steps. For finite geometric progression i.e. For limited numbers the process of finding the sum can be quite simple.

Geometric Series or Sequence is generally denoted by the term an. The formula for Geometric Series would look like

S = ∑ an = a1 + a2 + a3 + ... + am in which m is the total number of terms we want to sum.

Formula to find the sum of a geometric difference with the common ratio is expressed as

FAQs on Geometric Sequences

1. What is meant by Geometric Sequence?

Geometric Sequence is defined as the list of numbers where each term in the sequence is multiplied by a constant non-zero number called the common ratio.

2. How to Calculate a Geometric Sequence?

You can calculate Geometric Sequence easily by taking the help of the formula i.e. an = a1 * rn-1

Where an is the nth term of the sequence

a1 is the first term in the sequence

r is the common ratio
