comment Solve this differential equation $xy'(x)=y(ln(x)-ln(y))$
yes I did a mistake . So then I just have to solve the equation. When I find g(x) its a bit tricky to get y(x). Thanks

I come to a dead end. $g'(x)=lnx/x -e^{g(x)}/x$

I have come to this ,but not sure what to do after. Should I use substitution ?

my sequence with $a_0=5$ is increasing..

comment Limit of this recursive sequence and convergence
The fact that it converges to that limit how is it proved? Other answers proove the monotony only.is it enough ?

Next, we observe that {xn} is upper bounded by 1+2p√.How is this found guessed?

so it is correct to say that $|a_n|<1$ (boundary)

comment Bound of sequence
Yes I thought that it should be a real number. However I found 2 as $(n+1)/n^2$ seems decreasing.

comment Bound of sequence
I have to prove that sequence is bounded below and above. But dont know how to do it.

I dont know how to find the bound from that

comment Bound of sequence
then i get $\frac{n+1}{n^2}$ all examples I have seen are basic.
