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}.
