🔹 What is a Pattern?
A pattern is a sequence of numbers that follows a rule.
👉 Example:
2, 4, 6, 8, … (each time +2)
🔹 What is Number Theory?
Number Theory is a branch of Mathematics that studies numbers and their patterns.
🔹 What are Number Sequences?
A number sequence is an ordered list of numbers that follows a specific rule.
👉 Examples:
- 1, 2, 3, 4, … (Counting numbers)
- 2, 4, 6, 8, … (Even numbers)
- 1, 3, 5, 7, … (Odd numbers)
✍️ How to write in exam:
Patterns in Numbers:
“A pattern is a sequence of numbers that follows a certain rule.”
Number Sequence:
“A number sequence is an ordered list of numbers that follows a specific rule.”

👉 Pattern: All numbers have 1
✅ Next: 1, 1, 11, 2, 3, 4, 5, 6, 7, … (Counting numbers)
👉 Pattern: Adding +1
✅ Next: 8, 9, 101, 3, 5, 7, 9, 11, … (Odd numbers)
👉 Pattern: Add +2 (odd numbers)
✅ Next: 13, 15, 172, 4, 6, 8, 10, 12, … (Even numbers)
👉 Pattern: Add +2 (even numbers)
✅ Next: 14, 16, 181, 3, 6, 10, 15, 21, 28, … (Triangular numbers)
👉 Pattern: +2, +3, +4, +5, +6…
✅ Next:
28 + 8 = 36
36 + 9 = 45
45 + 10 = 551, 4, 9, 16, 25, 36, 49, … (Squares)
👉 Pattern: \((n^2) =(1^2, 2^2, 3^2,\dots)\)
