Number Patterns
Sequences of numbers that follow a specific arithmetic rule, such as adding, subtracting, multiplying, or dividing by a fixed number to get the next term.
Geometric Patterns
Visual designs and shapes that repeat or grow in a predictable sequence using dots, lines, or polygons.
Triangular Numbers
Numbers that can be represented as equilateral triangles of dots, starting with 1, 3, 6, 10, and so on, formed by adding consecutive integers.
Square Numbers
Numbers obtained by multiplying an integer by itself, forming a square grid of dots, such as 1, 4, 9, 16, and 25.
General Rule of a Pattern
An algebraic or arithmetic expression that helps find any term in a pattern without writing out all the preceding numbers.

Board Exam Info
In the Andhra Pradesh (BSEAP) Class 6 Mathematics examinations, this chapter typically carries around 4 to 6 marks. Common question types include filling in the missing numbers in a sequence, drawing the next figure in a geometric pattern, and explaining the rule behind a given number series.
Frequently Asked Questions
How do I find the missing number in a difficult number pattern?
First, find the difference between consecutive numbers. If the differences are not the same, check for multiplication, division, or combinations of operations like adding and multiplying.
What are triangular numbers and how are they formed?
Triangular numbers are formed by adding consecutive natural numbers (1, 1+2, 1+2+3, etc.), and they can be arranged visually to form equilateral triangles.
Are patterns only about numbers?
No, patterns can also be found in shapes, letters, colors, and everyday objects, such as floor tiles, clothing designs, and nature.
