Arithmetic Sequences

  • If you are given several terms of a sequence, use the formula for the nth term to find an algebraic expression for the nth term.

  • When finding arithmetic means, first use the formula for the nth term to find d. Then add d to the value before the unknown arithmetic means repeatedly to find the missing means.
