    1. Find the sum of the first five terms of the geometric sequence.
    A=3, r=2
    2
    a. 93 b. 5 c. 1 d. 93
    2 2

    2. Use the Gauss-Jordan method to solve the system of equations.

    x - y + 3z = 16
    3x + z = 4
    x + 2y + z = -4

    a. No solution b. (4, 0, -4) c. (0, -4, 4) d. (4, -4, 0)

    3. Perform the indicated operation. Give the answer in lowest terms.

    8p - 8 / 10p - 10
    P 6p^2

    a. 5 b. 80p^2 + 160p +80 c. 24p d. 48p^3 - 48p^2
    24p 6p^3 5 10p^2 - 10p

    1. Find the sum of the first five terms of the geometric sequence.
    A=3, r=2
    2
    a. 93 b. 5 c. 1 d. 93
    2 2
    The general term of the geometric sequence is
    , where n = 1, 2, 3, ...
    Or
    So the first five terms are:

    Therefore, the sum of ...
