M is the midpoint of segment AN, A has coordinates (6,2) and M has coordinates (1, 3). What are the coordinates of N?

1  (6) = +5
1 + 5 = 4
3 2 = 5
3 +(5) = 8
so
(4,8)
check
Is 1 halfway between 6 and +4
yes
Is 3 halfway between 2 and 8
yes 
Ok, I think I understand. so the coordinates of N are (4, 8)

yes

Graph it to see what I did.

Thanks so much! I get it now
