interval$?$

  • $\begingroup$ Is this the continuation of the "upper bound" questions like math.stackexchange.com/questions/1621089/… ? $\endgroup$ – gammatester Jan 28 '16 at 13:14
  • $\begingroup$ there is a slight change, before it was in the interval $[n^2,(n+1)^2[$, today it is in $]n^2,(n+1)^2-n[$ $\endgroup$ – reuns Jan 28 '16 at 13:34

Since you say an upper bound, $n^2+ n$ is.

    $\begingroup$ $n$ is a better bound, for that matter. $\endgroup$ – Wojowu Jan 28 '16 at 13:12
