Lucas Numbers

by Linda

This is one of the concepts I use when designing a new pattern. For an overview, please see Math for Craft Design.

Below is a bit of information about the numbers in the Lucas series and a few examples of how they're used.

The Series

The first few numbers are:
2, 1, 3, 4, 7, 11, 18, 29, 47, 76, 123, 199...

How to Get These Numbers

  1. Start with 2 and 1, add them together to get the next number in the series - 3. You must begin with 2 and 1 to get Lucas numbers.
  2. Add the last two numbers - 1 and 3 - to get the next number in the series - 4.
  3. Do this again - adding the last two numbers together - 3 and 4 - to get 7.
  4. Then add 4 and 7 to get 11, 7 and 11 to get 18, etc.
