  1. Consider the sequence 3, 9, … Homework Help ✎

    1. Assuming that the sequence is arithmetic with t(1) as the first term, find the next four terms of the sequence and then write a rule for t(n).

    2. Assuming that the sequence is geometric with t(1) as the first term, find the next four terms of the sequence and then write a rule for t(n).

    3. Create a sequence that begins with 3 that is neither arithmetic nor geometric. For your sequence, write the next four terms and, if you can, write a rule for t(n).
