About Number Sequences

A number sequence is an ordered list of numbers following a pattern. Sequences can help with calculations, predictions, and problem-solving in mathematics and science.

How It Works

Choose the type of sequence, provide initial terms or pattern parameters, and the tool will generate the sequence up to n terms, calculate sums, and display differences.

Advice

Check your input carefully. Arithmetic and Geometric sequences need a first term and difference/ratio. Fibonacci ignores difference/ratio. For custom sequences, separate numbers with commas.

FAQs

Can I generate more than 50 terms? Yes, but performance may slow down in browser.
What is the nth term? The calculator will automatically list all terms up to n.
Can I copy the result? Yes, use the copy button below the result.
