### What is a Geometric Sequence?

The geometric sequence in other words we can call geometric progression. A geometric sequence is a sequence of non-zero numbers by using the common ratio each term will be multiplied by its previous term. In the geometric sequence, we have finite and infinite terms. And if we see the formula of geometric progression.

an = a*rn - 1

where

r is the common ratio.

n is the number of terms.

### How to Find the Geometric Sequence?

Following are the guidelines that are given below to calculate the geometric sequence easily.

• Take the values that were given in the problem.
• After that, apply the formula.
• And substitute the values in the formula.
• Finally, you will get the answers.

Example:

Question: Find the geometric sequence up to 3 terms if first term(a) = 5, and common ratio(r) = 3.

Solution:

Given, r =3, a1 = 5.

As we know,

an = a*rn - 1

a1 = 5 × 31 - 1= 5.

a= 5 × 32 - 1= 15.

a3 = 5 × 33 - 1= 45.

Therefore, the geometric sequence is {5,15,45}
