Lessons

  1. Term-to-term rulesContinue a sequence, describe its rule, fill gaps, and generate terms from a rule or an nth term. 20 min, free
  2. The nth term of a linear sequenceFind the nth term from the common difference, and use it to test values and find positions. 25 min, with the Graphing Calculator, free
  3. Special sequencesSquare, cube and triangular numbers, Fibonacci-type sequences, and telling sequence types apart. 20 min, Plus
