How to use Arithmetic and Geometric Sequence Calculator
Arithmetic terms add a difference; geometric terms multiply a ratio. A bounded iterative compensated sum handles signed ratios and near-one values without subtracting nearly equal powers.
- Enter first term, difference or ratio, term count.
- Check the model, units, and supported limits before calculating.
- Run the tool, inspect the result, then copy or download it.
Good to know
- Whole count 0–10,000 and finite derived values. No infinite-series or convergence result. A zero count has no nth term.
- Runs locally. Numeric inputs are bounded; floating-point output is approximate and rounded to 12 significant digits. Unsupported or non-finite calculations produce an error.
