Answer:

18


Step-by-step explanation:


Average = sum / number of terms


First 4 numbers


Average = 16

Number of terms = 4


Sum / 4 = 16

= > Sum = 16 × 4

             = 64


Next 4 numbers


Average = 20

Number of terms = 4

Sum / 4 = 20

= > Sum = 20 × 4

              = 80


Total average


Total sum = 80 + 64

                 = 144


Number of terms = 8


Average = 144/8

               = 72/4

               = 36/2

               = 18
