Let a, b, and c e positive integers such that a < b < c.  The median of these three numbers is 20 while the arithmetic mean is 28.  What is the greatest possible value for c?

Because the median is 20, we know that \(b = 20\)

 

Now, we want to minimize a, so we can maximize c. 

 

Can you take it from here?
