Answer
$\frac{1}{2},\frac{8}{9},\frac{6}{5},\frac{16}{11},\frac{5}{3}$
Work Step by Step
$a_n=\frac{4n}{n+7}$
$a_1=\frac{4}{8}=\frac{1}{2}$
$a_2=\frac{4\times2}{2+7}=\frac{8}{9}$
$a_3=\frac{4\times3}{3+7}=\frac{12}{10}=\frac{6}{5}$
$a_4=\frac{4\times4}{4+7}=\frac{16}{11}$
$a_5=\frac{4\times5}{5+7}=\frac{20}{12}=\frac{5}{3}$
