    6 is the right answer i pretty sure

    Step-by-step explanation:

    3/2 (-2) ^ (n-1)

    3/2 (-2) ^ (3-1)

    3/2 (-2) ²

    3/2 (4)

    12/2

    which then if we simplify we get

    12/2=6

    6

    Step-by-step explanation:

    Substitute n for 3

    A (n) = 3/2 (-2) ^ (n-1)

    A (3) = 3/2 (-2) ^ (3-1)

    A (3) = 3/2 (-2) ²

    A (3) = 3/2 (4)

    A (3) = 12/2

    A (3) = 6
