What is it?

Making a number pattern means creating a sequence of numbers that follow a specific rule or logic. Each number in the sequence is related to the previous one in a predictable way. This rule helps us find the next numbers in the pattern.

Simple Example

Quick Example

Imagine you are counting how many samosas your local chaiwala sells every hour. If he sells 5 samosas in the first hour, 10 in the second, and 15 in the third, you can see a pattern. He is selling 5 more samosas each hour!

Worked Example

Step-by-Step

Let's make a pattern starting with 2, where each new number is 3 more than the previous one.

1. Start with the first number: 2
---
2. Apply the rule: Add 3 to the first number. So, 2 + 3 = 5
---
3. The second number is 5. Now, apply the rule again: Add 3 to the second number. So, 5 + 3 = 8
---
4. The third number is 8. Apply the rule again: Add 3 to the third number. So, 8 + 3 = 11
---
5. The fourth number is 11. Apply the rule again: Add 3 to the fourth number. So, 11 + 3 = 14
---
Answer: The number pattern is 2, 5, 8, 11, 14, ...

Why It Matters

Understanding number patterns is super important for problem-solving in maths and beyond. It's the basic idea behind algebra, data analysis, and even computer programming. Engineers use patterns to design structures, and financial analysts use them to predict market trends.

Common Mistakes

MISTAKE: Not finding the correct rule and just guessing the next number. | CORRECTION: Always check the difference or relationship between at least the first two or three numbers to find the exact rule.

MISTAKE: Applying the rule incorrectly (e.g., adding instead of subtracting, or multiplying instead of dividing). | CORRECTION: Double-check the operation (addition, subtraction, multiplication, division) and the number being used in the rule.

MISTAKE: Assuming the pattern is always simple (like 'add 2'). | CORRECTION: Some patterns can be more complex, like 'multiply by 2, then add 1' or 'add the previous two numbers'. Always look for a consistent rule.

Practice Questions

Try It Yourself

QUESTION: What is the next number in the pattern: 10, 20, 30, 40, ___? | ANSWER: 50

QUESTION: Find the next two numbers in the pattern: 3, 6, 12, 24, ___, ___? | ANSWER: 48, 96

QUESTION: A taxi charges Rs. 50 for the first kilometer and Rs. 15 for every additional kilometer. If a ride is 5 kilometers long, what is the total fare? (Hint: The fare for 1 km is 50, for 2 km is 50+15, and so on.) | ANSWER: Rs. 110

MCQ

Quick Quiz

What is the rule for the number pattern: 7, 10, 13, 16, ...?

Add 2 to the previous number

Add 3 to the previous number

Multiply by 2

Subtract 3 from the previous number

The Correct Answer Is:

The difference between 10 and 7 is 3, between 13 and 10 is 3, and between 16 and 13 is 3. So, the rule is to add 3 to the previous number.

Real World Connection

In the Real World

From planning your daily travel to understanding mobile data usage, patterns are everywhere. When you recharge your phone with a 'data pack' that gives you 1GB per day, you're relying on a pattern of consistent data allowance. Even predicting cricket match scores or managing inventory in a shop involves recognizing and using patterns.

Key Terms

PATTERN: A repeating sequence or design. | SEQUENCE: An ordered list of numbers or objects. | RULE: The specific instruction that tells you how to get from one number to the next in a pattern. | PREDICT: To guess what will happen next based on a pattern.
