Answer
The graph labeled as (c) matches the sequence.
Work Step by Step
$a_n=\frac{8}{n+1}$
$a_1=\frac{8}{1+1}=\frac{8}{2}=4$
$a_2=\frac{8}{1+2}=\frac{8}{3}$
$a_2=\frac{8}{1+3}=\frac{8}{4}=2$
...
$a_7=\frac{8}{1+7}=\frac{8}{8}=1$
...
$a_{10}=\frac{8}{10+1}=\frac{8}{11}$
The graph labeled as (c) matches the sequence.
