    Arithmetic sequence: must have a constant common difference.

    3/20-1/10 = (3-2) / 20=1/20

    5/30-3/20 = (10-9) / 60=1/60

    Difference is not constant, so no.

    Geometric sequence: must have a common ratio

    30/20 / (1/10) = 15

    5/30 / (3/20) = 100/90 = 10/9

    ratio is not constant, so no.

    The answer is (c) neither geometric nor arithmetic
