Answer 1

Answer: The answer is 22

Step-by-step explanation:

The question is based on word problem, and must be interpreted.

Firstly, let's represent the unknown number with y.

16+22+y [everything, divided by 3]

since their average is 20;

Then,

(16 + 22 + y)/3 = 20

(38 + y )/3 = 20

38+y = 60

y=60-38

y=22

Therefore, third number is 22.
