1. The problem statement, all variables and given/known data Let A = (0,1)[itex]\cap[/itex]Q Let (Xn) be an enumeration of A. Show that (Xn) diverges 3. The attempt at a solution I am not quite sure of what 'diverges' means. Does this simply mean that a tail of (Xn) diverges to +∞ or -∞? If this is what the definition is, I cannot see how (Xn) diverges. I would say instead that it converges to 1.
