That’s one way to construct it. Of course none of the infinite series
individually reaches the limit (otherwise the following ones :-P would go
above it?). Together they do. It is reached after exactly Aleph0 steps.

Are there ℵo partial sums 0.9, 0.99, 0.999, ... ?
If yes they can be combined to 0.999... .
Is the limit one of them?
