MAFS.912.F-IF.1.3 Recognize that sequences are functions, sometimes defined recursively, whose domain is a subset of the integers.

MAFS.912.A-CED.1.2  Create equation in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales

 

Learning Targets and Learning Criteria
  • define an arithmetic sequence as a sequence of numbers that is formed so that the difference between consecutive terms is always the same known as a common difference.

  • recognize arithmetic sequences as linear functions.

  • explain that a recursive formula tells me how a sequence starts and tells me how to use the previous value(s) to generate the next element of the sequence.

    • create a table from a list of numbers (sequence) by making the term number (position) the inputs and the elements the outputs.

    • find an explicit or recursive rule for a sequence.

    • write specified terms for a sequence, defined explicitly or defined recursively.

    • identify the variables and quantities represented in a real-world problem

    • graph a system equations or inequalities on the coordinate plane that represent all possible solutions to a real-world problem using appropriate labels and scales

      • define system of linear equations and solution of a system

        • create a system of equations or inequalities with two variables.
