What is it?

Finding a pattern means looking for things that repeat or follow a rule in a set of numbers, shapes, or events. It's like being a detective and spotting a hidden order. Once you find the rule, you can predict what comes next.

Simple Example

Quick Example

Imagine you see a series of colours: Red, Blue, Red, Blue, Red... What colour do you think will come next? It's Blue! You found the pattern: Red, then Blue, repeating.

Worked Example

Step-by-Step

Let's find the pattern in this series of numbers: 2, 4, 6, 8, ___, ___.

1. Look at the first two numbers: 2 and 4. What's the difference? 4 - 2 = 2.
---2. Look at the next two numbers: 4 and 6. What's the difference? 6 - 4 = 2.
---3. Look at the next two numbers: 6 and 8. What's the difference? 8 - 6 = 2.
---4. It looks like the pattern is 'add 2' to the previous number.
---5. To find the first missing number, add 2 to 8: 8 + 2 = 10.
---6. To find the second missing number, add 2 to 10: 10 + 2 = 12.

Answer: The next two numbers in the pattern are 10 and 12.

Why It Matters

Finding patterns is super important in many fields! Scientists use it to understand nature, data scientists use it to make predictions, and even AI uses it to learn. It helps us solve problems, make smarter decisions, and understand the world around us.

Common Mistakes

MISTAKE: Only checking the first two elements and assuming the pattern | CORRECTION: Always check at least 3-4 elements to confirm the pattern rule is consistent.

MISTAKE: Confusing adding/subtracting with multiplying/dividing patterns | CORRECTION: Test different operations (addition, subtraction, multiplication, division) to see which rule fits best.

MISTAKE: Not considering alternating patterns (e.g., add 2, then add 3) | CORRECTION: If a simple rule doesn't work, look for patterns that change or combine different rules.

Practice Questions

Try It Yourself

QUESTION: What comes next in this pattern: Triangle, Circle, Square, Triangle, Circle, Square, ___? | ANSWER: Triangle

QUESTION: Find the next number: 5, 10, 15, 20, ___ | ANSWER: 25

QUESTION: What are the next two numbers in this series: 1, 3, 6, 10, ___, ___? | ANSWER: 15, 21 (Hint: The difference between numbers increases by 1 each time: +2, +3, +4, +5, +6)

MCQ

Quick Quiz

Which number comes next in the pattern: 10, 9, 8, 7, ___?

The Correct Answer Is:

The pattern is decreasing by 1 each time (10-1=9, 9-1=8, 8-1=7). So, 7-1 = 6. Options A, C, and D do not follow this rule.

Real World Connection

In the Real World

Imagine you're watching a cricket match and a batsman scores 4, 6, 2, 4, 6, 2... If you find this pattern, you can guess what they might score next! Similarly, weather forecasters look for patterns in temperature and rainfall data to predict if it will rain tomorrow.

Key Vocabulary

Key Terms

PATTERN: A repeated arrangement or sequence | SEQUENCE: A set of numbers or objects in a particular order | RULE: The operation or logic that defines a pattern | PREDICT: To say what will happen in the future based on a pattern
