Answer
$a_{50}=1.75$
Work Step by Step
The nth term of an arithmetic sequence can be found using the formula:
$a_n=a_1+(n−1)d$
where
d = common difference
$a_1$ = first term
$a_n=n^{th}$ term
The given arithmetic sequence has:
$a_1=14
\\d=-0.25$
Use the formula above to find the 50th term:
$a_n=a_1+(n−1)(d)
\\a_{50}=14+(50−1)(-0.25)
\\a_{50}=14+49(-0.25)
\\a_{50}=14+(-12.25)
\\a_{50}=1.75$
