## Sequence Calculator For Arithmetic And Geometric Sequence

The number sequence is usually seen in the aptitudes and mind games probably. The sequence of objects or numbers in an ordered listed is termed as sequence calculation. The number sequences is often a mind game that is used to find a candidates potential in solving a problem with more simplicity. We could find many sorts of numbers sequencing in these days. However, we are taking the most obvious sequencing people always seek for.

This sequencing is posted in three different categories of calculators such us arithmetic number sequence calculator, geometric sequencing calculator and Fibonacci sequencing calculator. These calculators will be helpful for the people who are really desperate to get the answer for their sequence numbers questions.

Many officials use these number sequencing calculators to create the question for their candidates in some firms. Usually, this sequencing is often used for the games in some organizations. This quick sequencing will be helpful to improve their mind power and the working of their brains.

Let me explain working of the tools build for sequencing the numbers.

## Geometric Sequence calculator

Let me start with an interesting one in the row. The geometric calculator generates the sequence of numbers based on the inputs you provide. More specifically, this calculator generates the series up to the limit you have specified in it. This calculator will help you get the geometric series online without a sweat. Here I would like to explain the steps and geometric sequence formula that is used in the calculator.

## Geometric Sequence formula

Nth value of given number **fn = fn-1 * r**

Sum of the numbers **a(1-r n+1) / (1-r)**

This is the formula that is used in the geometric calculator to generate the number series.

## How To Calculate Geometric Series Online?

- Enter the first number of your series in the first box. (From this number your sequence will be started).
- Enter the common ratio (the difference between each number in your series) in the second box.
- Enter the number of sequence numbers you wish to obtain in the third box.
- Click the calculate button to get the answer.

Consider that your input is 1, 4 and 6 in three boxes respectively.

The result you will get is

Sequence :1,4,16,64,256,1024...

Value :1024

Sum of all numbers : 1365

## Fibonacci calculator

The Fibonacci is a sequence in which the third number will be the sum of first two numbers. The Fibonacci series starts with the values 0 and 1. Fibonacci sequence in nature is 0, 1, 0+1=1, 1+1=2, 1+2=3, 2+3=5, 3+5=8…… and so on. These Fibonacci series is used in the Fibonacci retracement and Fibonacci trading. The Fibonacci retracement is a used by the technical traders with some key numbers.

Therefore the series will be 0,1,1,2,3,5,8,13…

## Fibonacci Sequence Formula

You can use this Fibonacci sequence formula to get a sequence of your own. This is the formula in which the Fibonacci calculator works.

N th value of given number **f0 = 0 , f1 = 1 fn = fn-1 + fn-2**

## How To Use Fibonacci Sequence Calculator?

- Enter the number of sequence you wish to have in the box.
- Click enters to get the result.

Consider that you have entered 9

Then the series would be

Sequence :0,1,1,2,3,5,8,13,21...

Value :21

Sum of all numbers : 54

## Math Arithmetic Series/Sequence Calculator

This is one common calculator that people often use to get their math arithmetic series. The arithmetic sequence is generated by the arithmetic sequence formula. The arithmetic sequence is the sum of the first number with the ratio you should enter to generate the arithmetic series.

## The Arithmetic Sequence Formula

This is the arithmetic sequence formula that is used in this calculator to generate the series of arithmetic numbers.

N th value of given number **fn = fn-1 + f**

Sum of the numbers **n(f1 + fn) / 2**

## How to find arithmetic sequence?

You can easily find the arithmetic sequence with the online arithmetic calculator. for finding the arithmetic sequence

- Enter the first number in the first box.
- Enter the common ratio in the second box to generate the series.
- Enter the number of terms you want to take place in that number series.
- Finally click the calculate button to know your result.

If you have entered the pattern as 4,5 and 4. Then the arithmetic series generated would be

Sequence :4,9,14,19...

Value :19

Sum of all numbers :46
