Formula and method
This calculator computes Sum directly in your browser without sending data to an external server.
Mathematical formula
- Sum:
(n ÷ 2) × (2 × firstTerm+(n-1) × commonDiff)
Variables and parameters
- First term (a) (firstTerm): default value 3.
- Common difference (d) (commonDiff): default value 5.
- Number of terms (n): default value 10.
Some formulas are undefined for certain input combinations (such as division by zero or logarithms of non-positive numbers). In those cases the live tool displays an alert instead of NaN.
