The table below has a pattern. The top and bottom numbers are connected by a rule.
\begin{array} {|l|c|c|c|c|c|c|}
\hline
\rule{0pt}{2.5ex}\text{Top number} \rule[-1ex]{0pt}{0pt} &\ \ 1\ \ &\ \ 2\ \ &\ \ 3\ \ &\ \ 4\ \ & \ldots &\ \ ?\ \ \\
\hline
\rule{0pt}{2.5ex} \text{Bottom number} \rule[-1ex]{0pt}{0pt} & 3 & 6 & 9 & 12 & \ldots & 27 \\
\hline
\end{array}
What is the top number when the bottom number is 27?
- \(5\)
- \(6\)
- \(9\)
