The second term of a geometric sequence is $4.$ The fifth term is $\frac{4}{27} .$

Find $S_{3}$ for this sequence.

You are given

\begin{aligned} a r & = 4 \\ a r^{4} & = \frac{4}{27} \end{aligned}

Use

\frac{a r^{4}}{a r}

to find $r .$

Now you know $r,$ use

a r = 4

to find $a .$

\begin{aligned} S_{3} & = u_{1} + u_{2} + u_{3} \\ = a + a r + a r^{2} \end{aligned}
