    Answer:

    B 3/4

    Step-by-step explanation:

    The nth term of a geometric progression is given by

    an = a1 . rn – 1

    Where;

    an = the nth term

    a1 = the first term

    r = common ratio

    n = the number of terms in the series

    Common ratio, r = the ratio of the second term to the first term

    = a2 : a1

    Given from the series,

    a2 = 48

    a1 = 64

    Common ratio, r = 48 : 64

    = 48/64 = 3/4
