And just to prove this to you, let's make a little substitution here. Let's say that n is equal to, let me say 1 over n is equal to a over x, and then what would be x would be equal to n a, right, x times 1 is equal to n times a. And so the limit as x approaches infinity, what does a approach? a is, sorry, as x approaches infinity, what does n approach? Well, n is x divided by a, right? So n would also approach infinity. So this thing would be the same thing as just making our substitution.
