Number Series Calculator 97.0

Number Series Calculator is designed to assist in preparation for IQ Tests and Number Series Tests. It can be useful for self-learning the numerical sequences used in IQ Tests and Number Series Tests.
With Number Series Calculator you can find the next number in a number sequence and analyze many different types of number series (Fibonacci, Arithmetic progression, Geometric progression etc.) .

Also you can search our sequence database and use a question mark, for example, 1,?,?,4 or ?,?,3,4.

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

Number Series Calculator can
- find the next number in a number sequence
- search our 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 offline mode
