A) 3  B) 5.5  C) 6.25  D) 16  E) 7.5
GivenThe median of the list of positive integers above is 16   So arranging the numbers from lowest to highest, avg of 2 middle terms needs to be 16   so the sequence will be x 14 18 20   Lets say x = 12, which gives us mean = sum/4 = 16   16 is correct
<result>D</result>
