Calculates arithmetic mean (AM) between two numbers: AM = (a + b)/2. For n numbers, AM = (a₁ + a₂ + ... + aₙ)/n.
Arithmetic Mean = (a₁ + a₂ + ... + aₙ) / n
For two numbers a and b: AM = (a + b)/2
In AP, AM of three consecutive terms is the middle term
Arithmetic mean is the average of numbers

Inputs explained
- Numbers [required]: Array of numbers
Formula / method
Arithmetic Mean = (a₁ + a₂ + ... + aₙ) / n For two numbers a and b: AM = (a + b)/2 In AP, AM of three consecutive terms is the middle term. Arithmetic mean is the average of numbers (calculator id: arithmetic-mean-calculator).
Worked example
Worked values: numbers = [10, 20] → mean = 15, sum = 30, count = 2
Interpreting results
Cross-check with a simple numeric example before relying on extreme inputs for arithmetic mean.
Assumptions
- Empty required inputs are not silently replaced with zeros for arithmetic mean. [arithmetic-mean-calculator]
- Arithmetic Mean is computed only from the fields you enter on this calculator.
- Real-number arithmetic is used unless arithmetic mean explicitly needs integers.
Limitations
- If multiple conventions exist for arithmetic mean, this calculator uses the convention implemented in its engine path.
- This page does not provide a full textbook proof for every identity related to arithmetic mean.
- Complex/branch cuts and undefined points are not always interactively annotated for arithmetic mean.
Important note
Educational mathematics tool. Check edge cases and domain restrictions when results look unexpected.
