Answer
$\frac{6}{5}$
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.
$a_{15} = \frac{15+3}{15} = \frac{18}{15} = \frac{6}{5}$
