Patterns in Numbers

A number pattern is a list of numbers. This pattern generally follows a common relation between the list of the numbers.
There are two types of number patterns:

  • Increasing Number Pattern
  • Decreasing Number Pattern

Decreasing Pattern Example

If the numbers in the pattern are are decreasing by a particular order, then it is said to be in decreasing number pattern.
