Question

S, u, n are collinear. what point is between the other two if nu = 1, su = 2, sn = 3?

Answer 1

So the two most extreme points will be the ones with the biggest distance between them; this seem to be s and n since the distance between them is 3. The other point is u, and it seems to be between them, and indeed it's closer to n (nu is smaller than su), and it's between s and n (the answer is u)
