11-74.
  1. A sequence starts 24, 12, … Use that information to complete parts (a) and (b) below. Homework Help ✎

    1. If the sequence is arithmetic:

      1. Find t(3).

      2. Find t(n).

      3. What is the shape of its graph?

      4. Which term is −624?

    2. If the sequence is geometric:

      1. Find t(3).

      2. Find t(n).

      3. What is the shape of its graph?

      4. Which term is

Add (or subtract) the same amount again.

t(n) = 36 − 12n

Try graphing the sequence as a function.

Substitute −624 for t(n) and solve for n.

Multiply (or divide) by the same amount again.
