BIG IDEAS

  • I can crack a secret code, figure compound interest, and determine a retirement salary if given the same raise each year.
  • I will recognize that patterns exhibit relationships that can be extended, described, and generalized.


UNDERSTANDING THE STANDARD

  • Sequences and series arise from real-world situations.
  • The study of sequences and series is an application of  the investigation of patterns.
  • A sequence is a function whose domain is the set of natural numbers.
  • Sequences can be defined explicitly and recursively.
