How to Use the Calculator

To use this series calculator:

  1. Enter the number of terms in the series (n).
  2. Input the first term in the series (a1).
  3. Type in the common difference between the terms (d).
  4. Click the “Calculate” button to see the result.

How it Calculates the Results

The calculator uses the formula for the sum of an arithmetic series: S = (n/2) * (2 * a1 + (n – 1) * d), where:

  • n is the number of terms,
  • a1 is the first term, and
  • d is the common difference between terms.

By substituting the input values into this formula, we can calculate the sum of the arithmetic series.

Limitations

This calculator:

  • Only works with numeric input values.
  • Assumes that the series provided is an arithmetic sequence.
  • Does not handle very large numbers or numbers with more than 15 digits after the decimal due to precision limitations in JavaScript.
  • Displays an error message if all fields are not filled in.
