This free number sequence calculator can determine the terms (as well as the sum of all terms) of the arithmetic, geometric, or Fibonacci sequence.

Sequences (numerical patterns) are sets of numbers that follow a particular pattern or rule to get from number to number. Each number is called a term in a pattern.

Number sequences are ordered lists of numbers that follow a particular pattern or rule. These sequences can be either finite or infinite, and can have different types of patterns.
