In a botanical study, a researcher measured the heights of six sequentially planted trees. She noted that each tree was either thrice as tall or one-third as tall as the one to its right. Due to an error, some data in her notes was obscured. The partially recovered records show:
\[\begin{tabular}{|c|c|}
\hline
Tree 1 & \rule{0.5cm}{0.15mm} meters \\
Tree 2 & 27 meters \\
Tree 3 & \rule{0.5cm}{0.15mm} meters \\
Tree 4 & \rule{0.5cm}{0.15mm} meters \\
Tree 5 & \rule{0.5cm}{0.15mm} meters \\
Tree 6 & \rule{0.5cm}{0.15mm} meters \\
\hline
Average height & \rule{0.5cm}{0.15mm}\text{ meters} \\
\hline
\end{tabular}\]
What is the average height of these trees?
