🔢 Number Sequences: Find the Rule
A number sequence is an ordered collection of numbers that follows a particular rule.
For example:
2, 4, 6, 8, 10, …
Each term increases by 2.
So:
10 → 12 → 14
💡 Quick Trick
Whenever you see a sequence, compare two consecutive terms.
Ask yourself:
> “What changed?”
The rule might involve:
* Addition
* Subtraction
* Multiplication
* Division
* Repeated operations
* Combining earlier terms
Once the rule is clear, continuing the sequence becomes much easier.
Odd & Even Number Patterns
🟡 Odd numbers form the sequence:
1, 3, 5, 7, 9, 11, …
Even numbers form the sequence:
2, 4, 6, 8, 10, 12, …
Both sequences increase by 2.
Remember
Odd: 1, 3, 5, 7, 9…
Even: 2, 4, 6, 8, 10…
These are among the easiest sequences to recognize when revising Patterns Class 6.
🔺 Triangular Numbers: Build with Dots
Imagine placing dots in rows so that each new row contains one more dot than the previous row.
You get:
1, 3, 6, 10, 15, 21, …
The growth works like this:
1 = 1
1 + 2 = 3
1 + 2 + 3 = 6
1 + 2 + 3 + 4 = 10
The numbers can therefore be represented using triangular arrangements.
🎯 Easy Memory Rule
Think:
+2, +3, +4, +5, +6…
That produces:
1 afterward, 3, 6, 10, 15, 21
🟦 Square Numbers: A Pattern You Can See
Square numbers include:
1, 4, 9, 16, 25, 36, …
They correspond to:
1² = 1
2² = 4
3² = 9
4² = 16
5² = 25
6² = 36
Square numbers can also be represented using dots arranged in a square grid.
🤯 A Surprising Odd-Number Connection
Watch what happens when odd numbers are added:
1 = 1
1 + 3 = 4
1 + 3 + 5 = 9
1 + 3 + 5 + 7 = 16
Every total is a square number. The chapter explains this visually using layers of dots.
🚀 Quick Challenge
The first ten odd numbers add up to what?
Answer: 100
The pattern gives:
10² = 100
So there is no need to add all ten numbers separately.
🧊 Cube Numbers: Think in 3D
Cube numbers are:
1, 8, 27, 64, 125, …
They come from:
1³ = 1
2³ = 8
3³ = 27
4³ = 64
5³ = 125
A useful way to picture them is with small blocks.
A 2 × 2 × 2 cube contains 8 blocks, while a 3 × 3 × 3 cube contains 27 blocks.
This makes the difference between square and cube numbers easier to visualise.
✌️ Powers of Two: Keep Doubling
Consider:
1, 2, 4, 8, 16, 32, 64, …
What happens each time?
👉 The number doubles.
For example:
2 × 2 = 4
4 × 2 = 8
8 × 2 = 16
The sequence is one of the important examples included in the chapter.
🔢 Virahānka Numbers: Add the Previous Two
The Virahānka sequence is:
1, 2, 3, 5, 8, 13, 21, …
Here, each new term is obtained by adding the two preceding terms.
For example:
1 + 2 = 3
2 + 3 = 5
3 + 5 = 8
5 + 8 = 13
8 + 13 = 21
🧠 Your Turn
What comes after 21?
13 + 21 = 34
So the next number is:
34
🔍 Different Patterns Can Connect
One of the most interesting ideas in Patterns Class 6 is that separate sequences can have hidden relationships.
Consider:
1
1 + 2 + 1 = 4
1 + 2 + 3 + 2 + 1 = 9
The results are:
1, 4, 9, 16, …
These are square numbers.
🌟 The Key Idea
Don’t only ask:
“What comes next?”
Also ask:
“Why does this pattern happen?”
That question helps you understand the mathematics behind the sequence.
🔷 Shape Patterns: Maths Beyond Numbers
Patterns also appear in geometry. Shapes can be organised into sequences according to their sides, corners, lines, or other features.
For example:
🔺 3 sides → Triangle
🟦 4 sides → Square
⬟ 5 sides → Pentagon
⬢ 6 sides → Hexagon
The number of sides follows:
3, 4, 5, 6, 7, …
This connects shape sequences with number sequences.
✏️ How to Solve a Shape Sequence
When you face a shape-pattern question:
1. Look Carefully
Study every figure before deciding what changes.
2. Count
Check the sides, corners, lines, dots, squares, or triangles.
3. Compare
Look at how one figure changes into the next.
4. Find the Rule
Identify the repeated change.
5. Draw the Next Figure
Use the rule instead of guessing.
The chapter includes activities where students identify the rule and draw the following shape.
🌍 Where Can We Find Patterns?
Patterns are not limited to school mathematics.
They can be observed in:
🌌 Movement of stars and planets
🌦️ Weather
📱 Technology
🛒 Shopping
🍳 Cooking
🎮 Games
🧬 Genomes
🔬 Scientific work
The chapter connects mathematical patterns with everyday activities, technology, space, and healthcare.
This is why Patterns Class 6 is more than a chapter about sequences. It introduces a way of thinking that can be useful in many areas.
