PATTERN
Definition Of Pattern
A Pattern constitutes a set of numbers or objects in which all the members are related with each other by a specific rule.
More About Pattern
Pattern is also known as sequence.
There can be finite or infinite number of members in a pattern.
Examples of Pattern
The above pattern contains 2 identical groups with each group having 3 different images, a star followed by a bar, which is followed by 3 dots.

Solved Example on Pattern
Ques: Find the next three terms of the following pattern. 81, 79, 77, ___, ___, ___,...
Choices:
A. 79, 81, and 83
B. 83, 81, and 79
C. 75, 73, and 71
D. 79, 77, and 75
Correct Answer: C
Solution:
Step 1: The rule for the pattern is to count down by 2 repeatedly and continue the sequence to find the next 3 terms.
Step 2: So, the next three terms in the sequence are 75, 73, and 71.
Quick Summary
- A pattern is also known as a sequence.
- Patterns can be finite (having a limited number of members) or infinite (having an unlimited number of members).
- Members in a pattern are related to each other by a specific rule.

Frequently Asked Questions
Q: How do I find the rule in a pattern?
A: Look for a consistent relationship between consecutive numbers or objects in the pattern. This could be addition, subtraction, multiplication, division, or a combination of operations.
Q: Can a pattern have more than one rule?
A: While rare, some complex patterns may involve multiple rules or varying rules depending on the position in the sequence. Focus on finding the simplest, most consistent rule first.
