    Answer:

    1.5

    Step-by-step explanation:

    As the common difference is not same for all terms, the given sequence is a geometric sequence

    the standard formula for a geometric sequence is:

    a_n=a_1r^{n-1}

    The formula to calculate common ratio is:

    r =   \frac{a_n}{a_{n-1}}

    Dividing the term by previous term

    So,

    r = 12/8 = 18/12 = 27/18 = 1.5

    The value for common ratio will be:

    1.5 ..
