For example, 9, 27, 81, 243, ... has a common factor of 3 (each term is just the last term times 3). Yours is like this. Geometric sequences have an nth term of the form a f^{n1} where a is the first term, f is the common factor and n is the number of the term (nth term). With my example, the nth term is 9 3^{n1}, which reduces to 3^{n+1}. Can you do something like this for your sequence? Stephen La Rocque.>
