Respuesta :

ok seems that
if it passes through something, then the next pont is the last one divided by 2

(6,3)
6/2=3

(8,4)
8/2=4

so
(n,-2)
n/2=-2
multiply boht sides by 2
n=-4

n=-4
The answer would be -4 because each side is aparently divided by 2 so in order to find n you have to do 2 x -2 = -4
