    Answer:

    geometric with r = 2

    Step-by-step explanation:

    An arithmetic sequence has a common difference between consecutive terms

    6 – 3 = 3

    12 – 6 = 6

    24 – 12 = 12

    48 – 24 = 24

    96 – 48 = 48

    As we see the differences are not common, so not arithmetic

    A geometric sequence has a common ratio between consecutive terms.

    6 ÷ 3 = 2

    12 ÷ 6 = 2

    24 ÷ 12 = 2

    48 ÷ 24 = 2

    96 ÷ 48 = 2

    There is a common ratio of 2, so sequence is geometric

    with 5th term = 48
