$$a_n=sqrtn^2+3n-n$$



I tried rationalizing, but got nowhere.

  • A better way to post is to show how you did the rationalization and explain why you thought you could go nowhere. These things would make your post easy to be accepted and to receive more advices to help you.

            One-line joke

            A one-liner is a joke that is delivered in a single line. A good one-liner is said to be pithy - concise and meaningful. [1] Comedians and actors use this comedic method as part of their act, e.g. Jimmy Carr, Tommy Cooper, Rodney Dangerfield, Norm Macdonald, Ken Dodd, Stewart Francis, Zach Galifianakis, Mitch Hedberg, Anthony Jeselnik, Milton Jones, Shappi Khorsandi, Jay London, Mark Linn-Baker, Demetri Martin, Groucho Marx, Dan Mintz, Emo Philips, Tim Vine, Steven Wright and Henny Youngman and Arnold Schwarzenegger.

"Venison's dear, isn't it?" (Jimmy Carr) "An escala...
