Number Series Calculator can be useful for self learning the number sequences used in IQ Tests, Number Series Aptitude Tests and brain teasers .

This app will help you prepare for the IQ and Math Test and it's free, offline and fast !

Number Series Calculator can

- find the next term in a number sequence

- search our online sequence database (you can use ? symbol, for example ?, ?, 3, 4, 5)

- automatically detects the symbolic expression of the number sequence

- automatically detects the the type of the number sequence

- supports number sequences of up to 10 elements in length

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

- you can input simple math formula. 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. With Number Series Calculator you can find the next number and formula of the number sequence and analyze many different types of math series (Fibonacci, Arithmetic progression, Geometric progression etc.) .

This application works in two modes : offline and online.

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 of use.

1 - What is next term in the number sequence 1, ?, ?, ?, ?, 8, 13, ?, ?, 55

Result:

Next number: 89

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

Method: Fibonacci

2 - Find the next term in the number sequence 1, 1, ?, ?, ?, 8

Results:

1. Next number: 13

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

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

Method: Fibonacci

2. Next number: 7

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

Number 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 number : 7

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

Method: Common Differences

2. Next number: 7

Formula: 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 number : 64

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

Method: Common Differences

For best results run algorithm 2-3 times.
