  • A sequence is an ordered set of numbers that follows a pattern or rule
  • A term is a number in a sequence
  • A term to term rule describes how to find the next term in a sequence by using the previous term
  • Most sequences can be written knowing only the first term and the term to term rule
  • Some sequences are easier to determine using an nth term rule
  • To find the next term in a sequence, compare terms to deduce the term to term rule and apply the rule to the last given term
