Even numbers from 1 to 100

There are 50 even numbers from 1 to 100: 2, 4, 6, 8, 10, … 96, 98, 100. They are the multiples of 2, and each one is exactly 2 more than the one before. Their sum is 2 + 4 + … + 100 = 2,550, which equals 50 × 51.

How to create a list of even numbers

  1. Enter the Start number and End number. Both ends are included if they are even.
  2. Select Generate List. The total count appears above the list.
  3. Copy the list, or download it as TXT (one number per line) or CSV for spreadsheets.

Formula for the count of even numbers

For a range from a to b, find the first even number f ≥ a and the last even number l ≤ b. The count is (l − f) ÷ 2 + 1. From 7 to 31, f = 8 and l = 30, giving (30 − 8) ÷ 2 + 1 = 12 even numbers.

RangeCount of even numbersFirst → last
1 to 1052 → 10
1 to 100502 → 100
1 to 1,0005002 → 1,000
−10 to 1011−10 → 10 (includes 0)

Sum of consecutive even numbers

The first n positive even numbers add up to n(n + 1). For n = 10 that is 2 + 4 + … + 20 = 10 × 11 = 110. Pairing the first and last terms explains why: 2 + 20, 4 + 18, … each pair sums to 22, and there are 5 pairs.

Frequently asked questions

Is 0 included in the list?

Only if your range includes it. From −4 to 4 the list is −4, −2, 0, 2, 4.

What is the largest range I can list?

Any range that contains at most 10,000 even numbers, such as 1 to 20,000. Larger ranges show a message asking you to narrow them.

How is this different from the even number generator?

This page lists every even number in order. The Even Number Generator picks random ones.
