Are numbers infinite?
The sequence of natural numbers never ends, and is infinite. OK, 1/3 is a finite number (it is not infinite). There’s no reason why the 3s should ever stop: they repeat infinitely. So, when we see a number like “0.999…” (i.e. a decimal number with an infinite series of 9s), there is no end to the number of 9s.
