 Table of contents Meaning Types of Number Series How to Find the Next Number Strategies for Solving Number Series

## Meaning

Number series are like a sequence of numbers that follow a pattern, just like counting numbers but with a twist!

## Types of Number Series

• The next number in the sequence is obtained by adding a constant to the previous number.

Subtraction Series

• The next number in the sequence is obtained by subtracting a constant from the previous number.

Multiplication Series

• The next number in the sequence is obtained by multiplying a constant by the previous number.

Division Series

• The next number in the sequence is obtained by dividing the previous number by a constant.

Square Number Series:

• Each number in the series is the square of consecutive integers.
• Example: 1, 4, 9, 16, 25, 36...

Fibonacci Number Series:

• Begins with 0 and 1, where each subsequent number is the sum of the previous two numbers.
• Example: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34...

## How to Find the Next Number

Look for a Pattern:

• We need to see if there's a special way the numbers are changing each time.

• Once we figure out the pattern, we use it to find the next number in the series.

## Strategies for Solving Number Series

Start Simple:

• We begin by seeing if the numbers are going up by the same amount each time.

• We can count in our heads or use our fingers to help us find the next number.

### Solved Example

(i) If the series is 3, 6, 9, 12, ..., what's the next number?
Ans:
We can see that each number is going up by 3, so the next number would be 12 + 3 = 15.
