What does this tool do?
In an arithmetic sequence each term adds the step (2, 5, 8, 11 with a step of 3). In a geometric sequence each term multiplies by it (2, 6, 18, 54 with a ratio of 3). Choose the separator to get a list, a comma-separated row or one value per line.

Frequently asked questions
Can the step be negative or a decimal?
Yes. A negative step counts down, and decimals like 0.25 work for both sequence types.
Is the Number Sequence Generator free to use?
Yes. It is free, needs no account and has no daily limit.
