Math : QUARTER 1 : SEQUENCE

• Sequence


  An ordered list of numbers
• Sequence


  • Finite - has a last term
  • Infinite - no last term
• Term


  Each number in a sequence
• General term


  A mathematical expression or rule for generating the terms of a sequence
• Finding general term


  1. Identify pattern

  2. Substitute values into formula
• Finite sequence


  Domain is positive integers with a last term
• Infinite sequence


  Domain is positive integers without a last term
• Deriving general term


  1. Substitute values into formula

  2. Check if formula matches first few terms
• Alternating sign sequences use (-1)^n in general term
• Finite Sequence


  
  
• A sequence that has a last term, meaning it has a limited number of terms.
• Infinite Sequence
