A sequence starts

  1. If you wanted to find the term of the sequence, would an explicit equation or a recursive equation be more useful?

    Recall the definitions of explicit and recursive equations.


  2. Write the equation in “first term” form as you did in problem 7-108.

    Refer to problem 7-108 to recall what the first term form means.

  3. What is the term of the sequence?

    Insert for in the equation you found in part (b).

  4. Write the explicit equation for the sequence , , , ... in “first term” form.
