 Solution

Let $(V_n)$ be a convergent sequence in the Stone-Čech compactification of the natural numbers, with limit $V$. Each fixed $W\ne V$ occurs only finitely often: the Hausdorff property gives a neighbourhood of $V$ excluding $W$, and eventually the sequence is in that neighbourhood.

If $(V_n)$ were not eventually equal to $V$, infinitely many terms would differ from $V$. They could not take only finitely many distinct values, because each such value occurs only finitely often. Recursively select a subsequence of pairwise distinct terms, all different from $V$. It still converges to $V$, contradicting the preceding parts. HenceThis establishes no nontrivial convergent sequences in the Stone-Čech compactification for arbitrary sequences, including ones with repetitions.
