Explanation:
I believe it would be 16 miles, if he starts off at 6 miles on day one and goes up 1/2 mile every day, he would be up a mile every other day, basically on day 3 he would be at 7 and day 5 at 8 miles, if the pattern continues he would be at 16 miles by day 21.
        
             
        
        
        
Answer:
Third table
Step-by-step explanation:
For the relationship to be proportional
y/x = constant
First table y/x = 8/4 = 2    then 7/11 doesn't =2  so it is not 
Second table y/x =52/5 = 5    then 49/7 doesn't =5  so it is not 
Third table y/x = 3/6=1/2    then 5/10 = 1/2   then 7/14 = 1/2  it is proportional
Last table y/x = 6/3 = 2    then 11/8 doesn't =2  so it is not
