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
