Rules for pattern:

Learning objective: Students will be able to complete patterns following
rules.

 A repeating arrangement of numbers, colors and shapes are known as
pattern

 A numerical pattern is a sequence of numbers that has been created
based on a formula or rule called a pattern rule. Pattern rules can use
one or more mathematical operations to describe the relationship

between consecutive numbers in the pattern.

 There are two primary categories of numerical patterns.

1. When numbers in a pattern get larger as the sequence continues,
they are in an ascending pattern. Ascending patterns often involve
multiplication or addition.

Ex 1: 5, 10, 15, 20,

Here, 5 is added to the numbers to form a pattern
Ex 2: 2, 4, 8, 16, 32, ……

Here, 2 is multiplied to the numbers to form a pattern.

2. When numbers in a pattern get smaller as the sequence continues,
they are in a descending pattern. Descending patterns often involve
division or subtraction.

Ex 1: 30, 27, 24, 21, …..

Here, 3 is subtracted from the numbers to form a pattern.

Ex 2: 128, 64, 32, 16, ….

Here, 2 is divided from the number to form a pattern.
