Answer

$a_{50} = 252$

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 $a_1=7$ and $d=5$ to obtain: $a_{50} = 7 + 5(50-1) \\a_{50}= 7 + 5(49) \\a_{50} = 7 + 245 \\a_{50} = 252$
