Number Series Calculator is an application for self learning the number sequences used in the IQ Tests, Math Tests and Aptitude Tests.

This app is free and offline !

With Number Series Calculator you can

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

- find the next or missing term in a number sequence

- search our online sequence database

- detect the pattern of the number sequence

- copy and send results to other applications (please, touch and hold the list item to show the menu).

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

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

Number Series Calculator is designed to assist in preparation for IQ Tests and Number Series Aptitude Tests.

This application works in offline and online modes.

In online mode you can search our sequence database using a question mark, for example, 1,?,?,4 or ?,?,3,4.

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

Examples

1 - What is missing and next terms in the number sequence 1, ?, ?, ?, ?, 8, 13, ?, ?, 55

Result:

Next term: 89

Pattern: A[n] = A[n-1] + A[n-2], n = 1,2,3 ...

Method: Fibonacci

2 - Find the next and missing terms in the number sequence 1, 1, ?, ?, ?, 8

Results:

1. Next term: 13

Pattern: A[n] = A[n-1] + A[n-2], n = 1,2,3 ...

Sequence: 1, 1, 2, 3, 5, 8

Method: Fibonacci

2. Next term: 7

Pattern: A[n] = A[n-1] - A[n-2] + n, n = 1,2,3 ...

Sequence: 1, 1, 3, 6, 8, 8

3 - Find the next term in the number sequence 1, 2, 3, 4, 5, 6

Results:

1. Next term : 7

Pattern: A[n] = n, n = 1,2,3 ...

Method: Common Differences

2. Next term: 7

Pattern: A[n] = A[n-1] + 1, n = 1,2,3 ...

Method: Common Differences

4 - Find the next number in the sequence 1, 2, 4, 8, 16, 32

Result:

Next term : 64

Expression: A[n] = A[n-1] * 2, n = 1,2,3 ...

Method: Common Differences

For best results run algorithm 2-3 times.
