Common Ratio of Geometric Sequence Calculator: Are you looking for a tool that displays the sum of a geometric sequence? Then this calculator is for you. Just by giving input, you will get the output. Also provided with steps, definitions, formulas, and some solved examples.

## How to Find the Common Ratio of Geometric Sequence?

A geometric sequence is a collection of numbers, that are related by a common ratio.

The formula of the common ratio of a geometric sequence is,

an = a * rn - 1

where

n is the nth term.

r is the common ratio.

Let us see the steps that are given below to calculate the common ratio of the geometric sequence. Follow the guidelines carefully.

• First, give the values that are given in the problem.
• After that, apply the formula and substitute the values in it.
• Finally, you will get the answer.

Example:

Question: Calculate the  geometric sequence up to 2 terms if a = 4, and common ratio(r) = 3.

Solution:

Given: a = 4, r = 3

an = a*rn - 1

a1 = 4 × 31 - 1= 4.

a2 = 4 × 32 - 1= 4 x 3 = 12.

Therefore, the geometric sequence is {4, 12}.
