Answer

$a_{60} = 362$

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 $a_1=8$ and $d=6$ to obtain: $a_{60} = 8 + 6(60-1) \\a_{60}= 8 + 6(59) \\a_{60} = 8 + 354 \\a_{60} = 362$
