Normal subgroup $N$, subgroup $U$, then $UN/N = U/N$. Let $G$ be a group and $N \unlhd G$ a normal subgroup, $U \le G$ some subgroup. Then I guess $U / N$ is always some group, and moreover $U / N = UN / N$, because $...
But, taking $UN$ first, will be the smallest subgroup that contains both $U$ and $N$, which then gives us what we need to make sense of the quotient. Moreover, the second Isomorphism theorem gives us that $UN/N \cong U/(U\cap N)$.

Show that $4 - Un+1 < 1/2(4 - Un)$ Let Un be a sequence such that : U0 = $0$ ; Un+1 = $sqrt(3Un + 4)$ We know (from a previous question) that Un is an increasing sequence and Un < $4$ Show that $4$ - Un+1 <(or =) 1/...
$$4-\sqrt{3u_n+4}\le \frac 12 (4-u_n)\iff 4-\sqrt{3u_n+4}\le 2-\frac 12u_n\\\ \iff 2-\sqrt{3u_n+4}\le -\frac 12 u_n\iff 2+\frac12 u_n\le \sqrt{3u_n+4} \\\\\iff 4+2u_n+\frac14 u_n^2 \le 3u_n+4 \iff \frac14 u_n^2-u_n\le 0 \\\ \iff u_n\left(\frac14 u_n-1\right)\le0, $$ which holds since $0\le u_n <4.$
