Example Data Table

Sequence Type Input Terms Generated Average
Manual List 4, 8, 12, 16, 20 4, 8, 12, 16, 20 12
Arithmetic First = 5, Difference = 3, Count = 6 5, 8, 11, 14, 17, 20 12.5
Geometric First = 2, Ratio = 2, Count = 5 2, 4, 8, 16, 32 12.4
Range Start = 10, End = 40, Step = 5 10, 15, 20, 25, 30, 35, 40 25

Formula Used

The core mean formula is:

Average = (x₁ + x₂ + x₃ + ... + xₙ) ÷ n

Here, each term in the sequence is added to produce the total sum, and that total is divided by the number of terms. The calculator also computes median, minimum, maximum, variance, standard deviation, and running totals for deeper sequence analysis.

For arithmetic sequences, the generated terms follow aₙ = a₁ + (n - 1)d. For geometric sequences, the generated terms follow aₙ = a₁ × r^(n - 1).

How to Use This Calculator

  1. Select the sequence mode that matches your data source.
  2. Enter a manual list, arithmetic inputs, geometric inputs, or a start-end-step range.
  3. Choose the decimal precision and preferred variance type.
  4. Press Calculate Average to show the result above the form.
  5. Review summary metrics, generated terms, and the running-total table.
  6. Use the CSV or PDF buttons to save your result report.

Frequently Asked Questions

1. What does this calculator compute?

It calculates the average of a sequence and also shows helpful supporting statistics such as total sum, count, median, minimum, maximum, variance, standard deviation, and running totals.

2. Can I enter my own sequence values?

Yes. Use the manual list mode and separate values with commas, semicolons, spaces, or line breaks. The calculator reads the values and computes the average automatically.

3. Does it support arithmetic sequences?

Yes. Enter the first term, common difference, and number of terms. The calculator generates the sequence, then evaluates its average and related statistics.

4. Does it support geometric sequences?

Yes. Provide the first term, ratio, and count. The sequence is generated from those values, then the calculator finds the mean and other summary measures.

5. Why are variance and standard deviation included?

Average alone shows central tendency. Variance and standard deviation show how spread out the sequence values are, which helps compare different datasets more clearly.

6. What is the difference between sample and population variance?

Population variance divides by the full number of terms. Sample variance divides by one less than the number of terms, which is useful when the sequence is a sample.

7. Can I download the results?

Yes. After calculation, use the CSV button for spreadsheet-style output or the PDF button for a printable report of your results and sequence details.

8. What happens if my range settings are incorrect?

If the step direction cannot move from the start value toward the end value, the calculator shows an error so you can adjust the range settings.
