Answer
$a_{16}=39$
Work Step by Step
RECALL:
The $n^{th}$ term, $a_n$, of an arithmetic sequence can be found using the formula:
$a_n=a_1 + d(n-1)$
where
$a_1$ = first term
$n$ = term number
$d$ = common difference
Use the formula with $a_1=9$ and $d=2$ to obtain:
$a_{16} = 9 + 2(16-1)
\\a_{16}= 9 + 2(15)
\\a_{16} = 9 + 30
\\a_{16} = 39$
