I've been reading about the proof of irrational nos. and I often encounter this phrase: "decreasing sequence of positive integers must be finite". What does this actually mean? Can anyone explain or point me to a link.

Here's a link of one proof I've read re proof of irrational nos: http://mathforum.org/library/drmath/view/55839.html

Thanks in advance :)
