Answer
$a_{70} = 244$
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 $a_1=-32$ and $d=4$ to obtain:
$a_{70} = -32 + 4(70-1)
\\a_{70}= -32 + 4(69)
\\a_{70} = -32 + 276
\\a_{70} = 244$
