Understanding Number Sequences

Arithmetic Sequences

  • Difference between terms is constant
  • Example: 2, 5, 8, 11 (d=3)
  • nth term: an = a1 + (n-1)d
  • Common in linear patterns

Geometric Sequences

  • Ratio between terms is constant
  • Example: 2, 6, 18, 54 (r=3)
  • nth term: an = a1 × r^(n-1)
  • Common in exponential growth

Applications

  • Financial calculations
  • Population growth models
  • Pattern recognition
  • Problem-solving in math
