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.
