$a_0=5$ $a_1=5$ $a_2=\frac{5}{2}$ $a_3=\frac{5}{6}$ $a_4=\frac{5}{24}$

Work Step by Step

$a_n=\frac{5}{n!}$ $a_0=\frac{5}{0!}=\frac{5}{1}=5$ $a_1=\frac{5}{1!}=\frac{5}{1}=5$ $a_2=\frac{5}{2!}=\frac{5}{2\times1}=\frac{5}{2}$ $a_3=\frac{5}{3!}=\frac{5}{3\times2\times1}=\frac{5}{6}$ $a_4=\frac{5}{4!}=\frac{5}{4\times3\times2\times 1}=\frac{5}{24}$
