The purpose of this app is to help everyone learn how to solve problems with number and letter series that are used in various tests and exams as IQ Test or Job Aptitude Test. This app may be useful for all math lovers.

With the Number Series Calculator, you can learn to find the next and missing elements of sequences used in IQ tests, Math tests, Aptitude tests, Job assessment tests, and more. This app not only calculates the missing numbers and letters of the sequence, but also finds the formula and in some cases, the name of the sequence (Fibonacci Series, Arithmetic Progression, Geometric Progression, Prime Numbers etc) . You can also see a graphical representation of the sequence or your own function.

This app works offline and does not require an internet connection.

With Number Series Calculator you can

- calculate nth or missing items of the sequence

- calculate Sum of the N Terms of the sequence

- analyze many different types of math series ( Fibonacci series , Arithmetic Sequence, Geometric Sequence etc. )

- find the next or missing element in a number sequence

- find the next or missing letter in a letter sequence

- find the formula of an arithmetic sequence

- calculate partial sums (a Partial Sum is the sum of part of the sequence)

- use simple math expressions. For example you can input 1/2, 2/3, ?/4, 4/?, 5/6

- calculate the nth term of the custom formula

- calculate the value of the custom formula

- copy and send results to other applications

- you can see the sequence graph or the graph of your own function

Symbol ^ used to represent exponentiation. For example, 2^2 means 4 .

You can use this application to calculate your own math formula (javascript syntax).

For example, to calculate square numbers create custom formula and set expression to 'n * n'. If you want calculate sin or cos, create custom formula and set expression to Math.sin(n) or Math.cos(n). You can use any javascript function.

You can calculate any recursive formula, for example, 'a[n-1] + a[n-2]' .

Number Series Calculator can use custom formulas to calculate the next and missing numbers in the number series.

In addition to the next and missing numbers of the sequence, the application determines its type and formula (pattern).

To solve problems with letter sequences, you need to select your alphabet in the settings.

If your alphabet is not in the list, select 'Other' and enter all the letters of your

alphabets separated by a comma in the field that follows the list of alphabets.

Example a, b, c, d, e, f, g.

This app may also be helpful in preparing for the next tests:

- online assessment test for jobs

- employment assessment test

- pre employment assessment test

- pre employment screening tests

- employment aptitude test

- skills assessment test for employment

- number series reasoning test

Examples ( from IQ Test )

1. What number comes next in the arithmetic sequence ?

1,1,2,3,5,8,13

Result:

Next Number = 21

Sequence Name: Fibonacci Sequence

2. What number comes next in the math sequence ?

1,3,5,7,9,11,13,15

Result:

Next Number = 17

Sequence Name: Arithmetic Progression

3. What number comes next in the numeric sequence ?

1,2,4,8,16,32

Result:

Next Number = 64

Sequence Name: Geometric Progression

4. What number comes next in the numeric sequence ?

2,3,5,7,11,13,17

Result:

Next Number = 19

Sequence Name: Prime Numbers

For best results, please, run application 2-3 times.
