Answer 2

Answer:

$a_{6} = 15 / 4\\a_{13} = 13 / 3$

Step-by-step explanation:

G.T,

    $a_{n} = 5n / n+2$

 Then,

       $a_{6} = 5(6) / 6+2\\a_{6} = 30 / 8\\a_{6} = 15 / 4$

       

        $a_{13} = 5(13) / 13+2\\a_{13} = 65 / 15\\a_{13} = 13 / 3$

Hence, we get the answers,

                       $a_{6} = 15 / 4\\a_{13} = 13 / 3$
