Whether you want to find the first 10 odd numbers or the first 20 even numbers, this tool quickly provides the answer. It is particularly useful for situations where you need to list a set of odd or even numbers, such as in math exercises, programming algorithm tests, data analysis, and more.

How to Generate the First N Odd or Even Numbers?

To generate the first N odd or even numbers, you can use simple mathematical formulas to calculate each number's value.

• First N Odd Numbers: The formula for odd numbers is: Odd = 2 × Position - 1. For example, to find the first 5 odd numbers:
  • 1st odd number: 2 × 1 - 1 = 1
  • 2nd odd number: 2 × 2 - 1 = 3
  • 3rd odd number: 2 × 3 - 1 = 5
  • 4th odd number: 2 × 4 - 1 = 7
  • 5th odd number: 2 × 5 - 1 = 9
• First N Even NumbersThe formula for even numbers is: Even = 2 × (Position - 1) (assuming 0 is considered the first even number). For example, to find the first 5 even numbers:
  • 1st even number: 2 × (1 - 1) = 0
  • 2nd even number: 2 × (2 - 1) = 2
  • 3rd even number: 2 × (3 - 1) = 4
  • 4th even number: 2 × (4 - 1) = 6
  • 5th even number: 2 × (5 - 1) = 8
