Answer
$\frac{4}{7}$
Work Step by Step
To calculate $a_n$, we plug in $n$ to the general formula.
To calculate the result, we use PEMDAS (parentheses, exponentation, multiplication, division, addition, subtraction) to determine which operation is applied first.
$a_{6} = \frac{6-2}{6+1} = \frac{6-2}{7} = \frac{4}{7}$
