A pattern is something that repeats in a rule. Two common kinds:
β’ Repeating pattern β the same group repeats, like π΅π΄π΅π΄β¦
β’ Growing pattern β it gets bigger by the same amount each time, like 2, 4, 6, 8β¦
To continue a pattern, find the rule (what repeats or what is added) and apply it.
Worked example
Problem: What comes next: πΊπ΅πΊπ΅πΊ __ ?
- The rule is πΊπ΅ repeating, so next is π΅.
Answer: The rule is πΊπ΅ repeating, so next is π΅.
Number Patterns & Rules
In a number pattern, look at the gap between numbers to find the rule. The rule can be add, subtract, or multiply.
β’ 3, 6, 9, 12 β rule is +3.
β’ 40, 35, 30, 25 β rule is β5.
β’ 1, 2, 4, 8 β rule is Γ2 (doubling).
Worked example
Problem: Find the rule and next number: 2, 4, 6, 8, __
- Rule is +2, so next is 10.
Answer: Rule is +2, so next is 10.
