How to Find the Common Difference in the Arithmetic Sequence?

An arithmetic sequence is a set of numbers or objects. The sequence is a set of numbers that are separated with commas. An arithmetic sequence is also called arithmetic progression. An arithmetic sequence is in form of, 

a, a +d, a + 2d, a + 3d, a + 4d......

Now, we will see the formula for the arithmetic sequence,

an = a₁ + (n-1)d.

where

an = nth term of the sequence.

a₁ = 1st term of the sequence.

d = common difference.

To find the common difference, 

d = an+1 - an

Steps to calculate the common difference of arithmetic sequence

Look into the guidelines that are given below for calculating the common difference of arithmetic sequence.

  • First, give the values that are given in the problem.
  • After that, apply the formula to find the common difference.
  • Finally, you will get the answer easily.

Example:

Question: Find the common difference between the a2 and a3, if a1 = 23, n = 3, d = 5?

Solution:

Given  a2 and a5, a1 = 23, n = 3, d = 5, a4 = 20 

Apply the formula,

an = a₁ + (n-1)d.

a = 23 + (3 -1) * 5

= 23 + 10 = 33.

a= a4 + (n-1)d.

= 20 + (3-1) * 5

= 20 + 10 = 30.

d = an+1 - a= a- a= 33 - 30 = 3.

Therefore the common difference of arithmetic sequence is 3.
