    geometric sequence

    Find the missing terms in the geometric sequence 5, __, __, 20.48.


    I can't seem to come up with the right missing terms. The distance between the terms is never consistent.

    if it is a geomatric sequence then the missing terms are 5r,5r^2
    where r=\sqrt[3]{\frac{20.48}{5}}
