7-15.

For parts (a) and (b), find a recursive equation in an form for each sequence. (For a reminder about an form see the Math Notes box in Lesson 5.3.2.) For parts (c) and (d) find an explicit equation for each sequence. Homework Help ✎

  1. a1 = 108a
    an+1 = an+12

  1. ,,, …

    a(n + 1) = 2an

  1. Is the sequence arithmetic or geometric?
