About this tool
Sequence Generator is a free online tool. Generate arithmetic, geometric, Fibonacci and other common sequences.
Select a sequence type or enter a custom formula, set the starting value and number of items, and the tool generates a sequence and displays each item. Support arithmetic sequence (e.g. 2, 5, 8, 11...), proportional series (e.g. 3, 6, 12, 24...), Fibonacci sequence (1, 1, 2, 3, 5, 8...), Square series, cubic series, etc.
Custom formulas support basic operations and common functions: n², 2^n, n!,√n, etc. The tool calculates the top N items and displays the general term formula, the sum of the top N items, and the nature of the sequence (increasing/decreasing/bounded, etc.).
Numbers are widely used in mathematics, programming, and finance. Arithmetic sequences are used for time deposits, proportional sequences are used for compound interest, and Fibonacci sequences appear in nature and algorithms. Tools help visualize sequence patterns.
Sequence generation tool supports multiple sequences such as arithmetic sequences, proportional sequences, and Fibonacci sequences. Formulas and terms can be customized.
