## Arithmetic Sequence Definition

In Mathematics, **Arithmetic sequence** means a particular type of sequence in which **two consecutive terms** can be found by **adding** or **subtracting** the same constant **number** called the **common difference**.

To find the **next terms** of this sequence, we need to **add** a constant **number** in the **previous value**. Similarly, we can find the **previous** term of the **sequence** by **subtracting** the same **number** from the **next value** of the **sequence**.

**For example**, 2, 8, 14, and 20 are in Arithmetic sequence as there is a difference of the same number i.e. “**6**”. Similarly, we can write an arithmetic sequence using a **single value** and the **common difference** between the values.

## Arithmetic Sequence Formula

In general, the formula for Arithmetic Sequence is:

^{a}n =^{a}1 + (n-1)d

In the above formula,

^{a}n stands for the**nth term**of the sequence.^{a}1 is the**first term**of the sequence.- n is the
**total number**of terms. - d is the
**common difference**between the terms of the sequence.

## How to Calculate the Arithmetic Sequence?

To calculate the Arithmetic sequence, we only need to put the values in the above formula. If we know any two consecutive terms of the sequence or the first term with a common difference, we can find a sequence from them. Let us explain with an example to let you understand the process to calculate arithmetic sequences properly.

**Example 1:**

Find the nth term of the Arithmetic sequence with 12 numbers in total if the first term is 4 and the common difference is 7.

**Solution:**

As we know,

^{a}n =^{a}1 + (n-1)d

From the question, we know,

^{a}1= 4

n = 12

d = 7

So, we can find the nth term by putting values in the above formula.

^{a}12 = 4 + (12 - 1)7

= 4 + (11)7

= 4 + 77

^{a}12 = 81

**Example 2:**

Find the 3rd term of the sequence if the first term is 11 while the common difference is 21.

**Solution:**

From the question, we know,

^{a}1= 11

From the question, we know,

n = 3

d = 21

Also,

^{a}3 = ?

By putting values in the formula,

^{a}3 = 11 + (3 - 1)21

= 11 + 42

= 53

### FAQ | Arithmetic Sequence

**How do you find the pattern rule of a sequence?**

Every type of sequence has a particular pattern rule that can be found by analyzing the terms. For example, the pattern rule of an Arithmetic sequence can be found by addition or subtraction.

**What is the main principle of an arithmetic sequence?**

The main principle of an arithmetic sequence is the difference between two consecutive terms will remain constant throughout the sequence.

**How do you find the arithmetic Sequence?**

To find an arithmetic sequence, we only need to add the common difference in the first term to get the second term. Similarly, we can find the third term by adding the same constant number in the second term. In this way, we can find as many terms of the sequence as we need in it.

**How do I find the common difference in an arithmetic sequence? **

To find the common difference, we need to subtract the previous term from the upcoming one. In simple words, you need to subtract the first term from the second one.

**How do I find the nth term of an arithmetic sequence?**

To find the nth term of the arithmetic sequence, you need to follow this specific formula.

^{a}n =^{a}1 + (n-1)d
