# Arithmetic Sequence Calculator

## Introduction to Arithmetic Sequence Calculator

An arithmetic common difference calculator is an online free tool to find the arithmetic sequence with the given common difference. It uses the arithmetic formula to calculate all terms of the series. It also computes the nth time of the sequence.

In mathematics, sequence finding is an important concept. But it would be best if you found the common difference between two consecutive terms, which sometimes becomes difficult. That makes your manual calculations tricky. So here, we introduce online application software that can easily calculate the sequence with a given common difference.

## How does the arithmetic sequence formula work?

An arithmetic sequence is an ordered set of numbers which have some difference between the consecutive terms. The arithmetic formula is given as:

$$a_n \;=\; a_1 \;+\; (n \;-\; 1) \;×\; d$$

Where

an = is the nth term or general term of the sequence

a1 = is the first term of the sequence

n =is the number of terms to be calculated

d = is the common difference between two consecutive terms.

Arithmetic sequence calculator can find the sequence by using input. You have to enter the values of a1,n and d to find the sequence. It also computes the sum of the number of terms of the sequence. The formula for finding sum of first n term is given as:

$$S_n \;=\; \frac{n}{2}[2a_1 \;+\; (n \;-\; 1) \;×\; d]$$ Example:

Calculate the arithmetic sequence for

$$a_1 \;=\; 4 ,\; d \;=\; 5 \;and\; n \;=\;3$$ Solution:

We will use arithmetic formula to solve this example which is:

$$a_n \;=\; a_1 \;+\; (n \;-\;1) \;×\; d$$

Using the given values,

$$a_3 \;=\; 4 \;+\; (3 \;-\; 1) \;×\; 5$$ $$a_3 \;=\; 4 \;+\; (2 \;×\; 5)$$ $$a_3 \;=\; 4\; +\;10 \;= \; 14$$

Now to find the Sum of first 3 terms we use the following formula.

$$S_n \;=\; \frac{n}{2}[2a_1 \;+\; (n \;-\; 1) \;×\; d]$$ $$S_3 \;=\; \frac{3}{2}[2 \;×\; 4 \;+\; (3 \;-\; 1) \;×\; 5$$ $$S_3 \;=\; \frac{3}{2} (8 \;+\; 10)$$ $$S_3 \;=\; \frac{3\; ×\; 18}{2} \;=\; 3 \;×\; 9$$

So the sum of first 3 terms is,

$$S_3 \;=\; 27$$

Arithmetic sequence is also known as arithmetic progression that can be simply denoted as AP.

## Why use an Arithmetic sequence calculator with a solution?

In mathematics, it is necessary to understand things based on patterns. The term arithmetic sequence enables you to understand the concept of pattern-based sequences. The arithmetic sequence formula calculator helps you to understand this concept.

While using the term arithmetic sequence in solving problems may use the wrong formula. But since this concept is formula-based, using the wrong formula may give false results. That’s why you need to use an arithmetic sequence calculator.

All of the math concepts play an essential role in our real life and other subjects like physics. But our learning and calculation methods should be updated by using technology. The arithmetic sequence is made to bring innovation to mathematics.

## Benefits of using arithmetic calculator:

In mathematics, an arithmetic progression is a sequence of numbers such that the difference between consecutive terms is fixed. There are many benefits of arithmetic sequence difference calculator that are bellowed:
