#### Answer

$a_{1}=-24$, $a_{2}=-4$, $a_{3}=-\displaystyle \frac{2}{3}$, $a_{4}=-\displaystyle \frac{1}{9}$, $a_{5}=-\displaystyle \frac{1}{54}$

#### Work Step by Step

$a_{1}=-24$, $a_{2}=\displaystyle \frac{-24}{6}=-4$ $a_{3}=\displaystyle \frac{-4}{6}=-\frac{2}{3}$ $a_{4}=\displaystyle \frac{-\frac{2}{3}}{6}=-\frac{2}{18}=-\frac{1}{9}$ $a_{5}=\displaystyle \frac{-\frac{1}{9}}{6}=-\frac{1}{54}$
