$a_1=216$ $a_2=36$ $a_3=6$ $a_4=1$ $a_5=\frac{1}{6}$

Work Step by Step

$a_3=6,~~a_4=1$ $r=\frac{a_4}{a_3}=\frac{1}{6}$ $r=\frac{a_3}{a_2}$ $\frac{1}{6}=\frac{6}{a_2}$ $a_2=36$ $r=\frac{a_2}{a_1}$ $\frac{1}{6}=\frac{36}{a_1}$ $a_1=216$ $r=\frac{a_5}{a_4}$ $\frac{1}{6}=\frac{a_5}{1}$ $a_5=\frac{1}{6}$
