What is it?
Predicting a pattern means figuring out what item or number will come next in a sequence by understanding the rule that connects the items. It's like being a detective and finding the hidden rule to complete a series.
Simple Example
Quick Example
Imagine you see a row of colours: Red, Blue, Red, Blue, Red, ___. What colour comes next? The pattern is 'Red, Blue' repeating, so the next colour is Blue.
Worked Example
Step-by-Step
Let's find the next number in this pattern: 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 pair: 4 and 6. What's the difference? 6 - 4 = 2.
---
3. Look at the next pair: 6 and 8. What's the difference? 8 - 6 = 2.
---
4. We see a rule! Each number is 2 more than the one before it. This is an 'add 2' pattern.
---
5. To find the next number, we add 2 to the last number (8).
---
6. 8 + 2 = 10.
So, the next number in the pattern is 10.
Why It Matters
Common Mistakes
MISTAKE: Guessing the next item without finding the rule | CORRECTION: Always find the rule first by looking at how the items change from one to the next.
MISTAKE: Assuming the rule is always 'add' or 'subtract' | CORRECTION: Patterns can also involve multiplying, dividing, or even changing shapes and colours. Look for all kinds of changes.
MISTAKE: Only checking the first two items to find the rule | CORRECTION: Check at least three or four pairs to confirm the rule. Sometimes a pattern might look like one thing at first, but then change.
Practice Questions
Try It Yourself
QUESTION: What comes next in the pattern: Circle, Square, Circle, Square, ___? | ANSWER: Circle
QUESTION: Find the next number: 10, 20, 30, 40, ___? | ANSWER: 50
QUESTION: What is the next letter in the series: A, C, E, G, ___? (Hint: Think about the alphabet) | ANSWER: I (The pattern skips one letter each time: A (B) C (D) E (F) G (H) I)
MCQ
Quick Quiz
What is the next shape in this pattern: Triangle, Triangle, Square, Triangle, Triangle, Square, ___?
Triangle
Square
Circle
Rectangle
The Correct Answer Is:
A
The pattern is 'Triangle, Triangle, Square' repeating. After 'Triangle, Triangle, Square', the pattern starts again with 'Triangle'.
Real World Connection
In the Real World
When you watch a cricket match, commentators often predict how many runs a team might score based on their current run rate and how many overs are left. This is a type of pattern prediction. Similarly, apps like Ola or Uber predict your arrival time by recognizing patterns in traffic data.
Key Vocabulary
Key Terms
PATTERN: A repeated arrangement of numbers, shapes, or items | SEQUENCE: A set of numbers or items that follow each other in a particular order | PREDICT: To say what will happen in the future based on current information | RULE: The instruction or method that creates a pattern.
