Answer:

3 + 5n

Step-by-step explanation:

This is an arithmetic sequence.

First term = a = 8

Common difference = d =Second term - first term

                                = 13 - 8

                                 = 5

Nth term = a + (n- 1)*d

              = 8 + (n -1) * 5

             = 8 + n*5 - 1 *5

              = 8 + 5n - 5

               = 8 - 5 + 5n

                = 3 + 5n
