Oct 28, 2015 at 20:21 comment added Joel David Hamkins A simple diagonalization like $y_n=x^{(n)}_n$ does not necessarily work---it may not go to $\infty$---since perhaps the original sequences $x^{(k)}$ only get large for values of $n$ much larger than $k$. But ultimately, the Hausdorff gaps are filled by a diagonalization procedure, as Andreas describes.
