For a geometric series, S4/S8=1/17. Determine the first 3 terms of the series if the first term is 3.

Since you are talking about a series, not just a sequence, does Sn mean the SUM of the first n terms?

Yes, I apologize for not clarifying. Sn refers to the sum of n terms.
Hm... perhaps I made a mistake somewhere, but I'm finding it impossible to find the answer to this question. Given only the two pieces of information in the OP: \(\displaystyle \dfrac{S_4}{S_8} = \dfrac{1}{17}\) and \(\displaystyle a_0 = 3\), I find that there are two real solutions for the common ratio r.
