Answer:Step-by-step explanation:You are finding the first term of a geometric sequence. What's given in the problem The second term of the geometric sequence is \(\frac{3}{4}\). The fourth term of the geometric sequence is \(3\). Helpful information The \(n\)-th term of a geometric sequence is given by \(a_{n}=a\cdot r^{n-1}\), where \(a\) is the first term and \(r\) is the common ratio.
