Analysis- Subsequences
For the given sequence, find the set S of subsequential limits

Wn= (0,1,2,0,1,3,0,1,4...)

I know the answer to be

S={0,1,infinity}

I am just trying to figure out what the subsequences are.

I tried thinking of them to be
Vn=(0,0,0,0...)
Xn=(1,1,1,1...)
Un=(2,3,4,5...)

please let me know if I am correct on this.

Those are correct. But the subsequence $u_n$ is not unique.
So you cannot list the subsequences.
