The online arithmetic sequence calculator is the best free tool that helps you to calculate the arithmetic sequence in split seconds. By giving the inputs in the input fields and by clicking on the calculate button immediately you will see the result on the calculator page.

Enter first term (a)
Enter difference (d)

How to Find Arithmetic Sequence Equation?

In maths, the sequence is defined as a set of numbers that are given in order. The sequence is simply a set of numbers separated by commas. As we have different types of sequences one of them is the Arithmetic sequence.

An arithmetic sequence is nothing but a sequence of numbers that are produced by adding a constant term as common difference. 

If we see the formula of arithmetic sequence equation,

a= a1 + d (n-1)

Here, 

a= nth term of sequence.

a1 = 1st term of sequence.

d = common difference.

Steps to Calculate the Arithmetic Sequence Equation

Take a look at the guidelines that are given below to calculate the arithmetic sequence equation easily.

  • Take the values that are given in the problem.
  • After that apply the formula, a= a1 + d (n-1).
  • Finally, you will get the arithmetic sequence equation.

Example:

Question: Find the arithmetic sequence equation, if a1 = 4, d = 5, n = 5?

Solution:

Given, a1 = 4, d = 5, n = 5

Now apply the formula of arithmetic sequence equation,

a= a1 + d (n-1)

= 4 + 5(5-1)

= 4 + 5 ( 4)

= 4 + 20

= 24

Arithmetic sequence equation is 4, 9, 14, 19, 24.
