Consider a geometric sequence \((a_{n})_{n=1}^{\infty }\).
Let \(q\) be the quotient
and \(s_{n}\) be the sum
of the first \(n\)
terms. Given \(a_{1} = -1\: 000\)
and \(a_{2} = 100\),
find the sum of the first four terms of the sequence.
\(s_{4} = -909\)
\(s_{4} = -900\)
\(s_{4} = 911\)
\(s_{4} = -911\)
