Can this calculator handle negative common differences?

Yes, entering a negative difference will calculate terms that decrease consistently across the sequence.

What if I only need the nth term without the sum?

The tool provides both outputs, but you can ignore the sum result if only the specific term value is required.

Does the tool support fractional or decimal starting values?

Input fields accept numeric values, including decimals and fractions, to fit various sequence patterns.

Is there a limit to how large the position number can be?

Very large position numbers will produce large results; the calculator follows standard arithmetic progression formulas without imposed caps.
