Even and Odd Test

Even and Odd Numbers List

See a range of integers divided into two columns, evens on one side and odds on the other, with a count for each. It is a quick way to show how the two kinds of number alternate.

Split a range into even and odd

Both ends are included. Up to 10,000 numbers per list; negative ranges work too.

From 1 to 50 there are 50 integers: 25 even and 25 odd.

What this list shows

For any start and end value, the tool lists every integer in the range and places it in the even or odd column. The summary gives the total number of integers and how many fall into each group. The CSV download keeps every number in its original order with a parity label, which is ideal for sorting or charting in a spreadsheet.

How to use it

  1. Enter the first and last numbers of the range.
  2. Select Generate List to see the two columns.
  3. Download the CSV for a number,parity table, or TXT for two labelled lists.

How many evens and odds does a range contain?

Even and odd numbers alternate, so a range of N consecutive integers splits as evenly as possible. If N is even, exactly half are even and half are odd. If N is odd, one group has one extra member, and it is the group that the range starts (and ends) with.

0 to 101165
−5 to 51156

Teaching with side-by-side lists

Ask learners to describe the pattern they see in each column: both increase by 2 every step, the last digits cycle through 0, 2, 4, 6, 8 and 1, 3, 5, 7, 9, and each odd number sits exactly between two even ones. Extending the range below zero shows that the pattern doesn’t break at zero, a natural lead-in to why zero is even.

Frequently asked questions

What is the maximum range?

Up to 10,000 integers in total, for example 1 to 10,000.

Can I use negative numbers?

Yes. Ranges such as −100 to 100 work the same way.

What is the difference from the Even Odd Calculator?

This list covers consecutive integers. The Even Odd Calculator checks any numbers you type or paste, in any order.
