Overview
Sequence Calculator helps you compute arithmetic and geometric progressions, including first-n sums, nth terms, formula display, and term list preview.
Key Features
- Arithmetic sequence calculation with first term, common difference, and term count.
- Geometric sequence calculation with first term, common ratio, and term count.
- Formula display for nth term and sum, useful for teaching and verification.
- Sequence preview for up to 20 terms to quickly inspect progression behavior.
How To Use
- Enter the first term and difference/ratio in the target section.
- Enter term count n as a positive integer.
- Results update automatically after inputs are complete.
- Use "Fill Example" for quick testing, or "Reset" to clear the current section.
Use Cases
- Math exercises and answer checking for sequence problems.
- Classroom demonstrations of arithmetic and geometric patterns.
- Exam preparation with fast formula verification.
- Basic series estimation in engineering and data work.
Notes
- n must be a positive integer.
- Very large values can overflow numeric limits; reduce input size if needed.
- All calculations run locally in your browser.
