The number before infinity?

Infinity itself isn't a number in the conventional sence therefore not only is there everything before it there is nothing Ie. If 10,000 were the value of infinity I could add 1 to it and that would become infinity so unless somebody finds the point at which numbers stop ascending there will never be a value before infinity, find ding that point is impossible because as I have said before if you pick a number you can always add 1 to it.
