### 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,

a_{n} = a₁ + (n-1)d.

where

a_{n} = nth term of the sequence.

a₁ = 1st term of the sequence.

d = common difference.

To find the common difference,

d = a_{n+1} - a_{n}

**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 a_{2} and a_{3}, if a_{1} = 23, n = 3, d = 5?

**Solution:**

Given a_{2} and a_{5}, a_{1} = 23, n = 3, d = 5, a_{4} = 20

Apply the formula,

a_{n} = a₁ + (n-1)d.

a_{2 } = 23 + (3 -1) * 5

= 23 + 10 = 33.

a_{5 }= a_{4} + (n-1)d.

= 20 + (3-1) * 5

= 20 + 10 = 30.

d = a_{n+1} - a_{n }= a_{2 }- a_{5 }= 33 - 30 = 3.

Therefore the common difference of arithmetic sequence is 3.
