Number Patterns
A sequence of numbers arranged according to a specific rule, such as adding a fixed number or multiplying by a constant.
Geometric Patterns
Visual designs and shapes that repeat themselves in a predictable manner, often seen in rangoli, tiles, and borders.
Triangular Numbers
Numbers that can form equilateral triangles, such as 1, 3, 6, 10, formed by adding consecutive natural numbers.
Square Numbers
Numbers obtained by multiplying a whole number by itself, such as 1, 4, 9, 16, which can form square grids.
Rule Identification
The process of finding the underlying mathematical relationship or formula that generates a given sequence.

Board Exam Info
In the Bihar Board 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 pattern, and identifying the underlying rule for a given series of numbers or shapes.
Frequently Asked Questions
What is the easiest way to find the rule in a number pattern?
Find the difference between consecutive numbers. If the difference is the same, it is an addition or subtraction pattern. If not, check for multiplication or division.
Are geometric patterns asked in the Bihar Board exam?
Yes, questions often ask you to draw the next two shapes in a repeating design or identify a symmetrical pattern.
How do I calculate triangular numbers quickly?
You can use the formula n(n + 1) / 2, where n is the position of the triangular number in the sequence.
