This arithmetic sequence nth term calculator helps when first term, common difference, n are already known and you want the nth term quickly.
Informational calculator only. Verify important outputs independently before legal, tax, medical, engineering, safety-critical, contractual, employment, or compliance use.
Enter job values, review the estimate, then use the decision hints before ordering or quoting.
a_n = a_1 + (n - 1)dStart from the first term and add the common difference enough times to reach term n.
This page assumes a standard arithmetic progression.
Keep geometric sequence nth term calculator math tidy when a plan, worksheet, or note set needs one quick calculation.
Next: arithmetic sequence sum.
Next: sum of natural numbers.
Keep more decimal places when the result will be reused in another formula, drawing, or comparison rather than read once and rounded.
Yes. The formula is stable and this tool only covers straightforward calculation.
