Key Topics to Revise

1

Algebraic Form of Sequences

  • A sequence is an arrangement of numbers according to a definite rule
  • Algebraic form expresses the relationship between position (n) and term value
  • General notation: x₁, x₂, x₃, ... for first, second, third terms respectively
2

Finding Algebraic Forms - Step by Step Methods

  • Method 1: Use first term and common difference formula
  • Method 2: Use two known terms to find constants
  • Method 3: Identify pattern and express algebraically
3

Sum of Arithmetic Sequences

  • Sum formula derived from pairing first and last terms
  • Gauss method: pair terms equidistant from ends
  • Two main formulas for calculating sums
4

Special Sequences and Applications

  • Sum of first n odd numbers = n²
  • Sum of first n even numbers = n(n+1)
  • Multiples of any number form arithmetic sequences
