I am a student in Mathematics at Boise State University.
My main interests lie in the realms of set theory and topology, but I have a deep appreciation for most fields of mathematics.

Here is the mathjax tutorial for this website: MathJax basic tutorial and quick reference

comment let $(a_n)$ be a sequence of real numbers such that $|a_{n+1}-a_n|\leq \frac {n^2}{2^n}$ for all $n\in \mathbb N$. Then
@copper.hat Maybe you can explain how gloom's solution is lacking, he applied some infinite triangle inequality thing that isn't really a triangle inequality thing--his indices are going upwards not downwards as in your hint. It seems that his solution is being upvoted which has correlation with correct-ness but in my opinion his solution is lacking...

I have written a solution, hopefully it makes sense to the community.

You're not quite applying the hint from copper.hat. He is applying the triangle inequality multiple times downwards, I'm not sure what's happening with your explanation.

@bof That makes sense. Yeah, I didn't think very deeply about the question...

comment No-where dense sets in the reals
@AsafKaragila Yes!!! those are the things that I mean by that. I guess weird to me is just simply things I have less familiarity with. I've played with vitali sets, and cantor space a lot-- fat cantor sets yeah, those are nice. But bernstein sets! I need to play with those some more... I'm a newcomer to desc. set theory so weird means unfamiliar :)
