Answer:

-8 + 12n

Step-by-step explanation:

First term = a = 4

Common difference = d = second term - first term

                                 = 16 - 4

                                 = 12

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

              = 4 + (n - 1)*12

              = 4 + n*12 - 1*12

               = 4 + 12n - 12

               = 4 - 12 + 12n

                = -8 + 12n
