Number Patterns

Definition of Number Pattern
A set (list) of numbers that perform certain series (pattern) like addition or multiplication repeatedly is termed as number pattern.

• In a number pattern, the numbers change in the same way each time
• Patterns are repetitive sequences
• Can be found in nature, shapes, events, sets of numbers, etc.
• Examples : geometric designs on quilts or tiles, the number sequence, seeds in a sunflower, snowflakes, etc.

Rule of Number Pattern

A pattern rule tells us how to build a pattern.

Here is a number pattern :

The numbers can be added, subtracted or multiplied.

Types of Number Pattern

• Triangular/ Triangle Numbers
• Square Numbers
• Cube Numbers

Here are the examples with solutions :

Triangular/ Triangle Numbers

Example 1

By adding another row of dots and counting all the dots we can find the next number of the sequence :

The Triangular Number Sequence is generated from a pattern of dots which form a triangle.

But it is easier to use this rule :

Example 2

Square Numbers

Example 3

Cube Numbers

Example 4
