I suppose that at least some of these can be considered duplicates. The question is, which of them should be left open and which ones should be closed:

Q: How to show that $\lim \frac{1}{n} \sum_{i=1}^n \frac{1}{i}=0 $?

GiiovannaShow that $$\lim \frac{1}{n} \sum_{i=1}^n \frac{1}{i} =0 $$ I've proved that this sequence converges (it is bounded and decreasing). NOW, I need to find a sequence that is bigger than this one and goes to zero. Maybe something using geometric serie of 1/2 Thanks in advance!

Q: Prove that $\lim_{n\to\infty} H_n/n = 0$ ($H_n$ is the $n$-th harmonic number) using certain techniques

BCLCI can't seem to use certain methods such as $\varepsilon$-N, L'Hôspital's Rule, Riemann Sums, Integral Test and Divergence Test Contrapositive or Euler's Integral Representation to prove that $\lim_{n-> \infty} \frac{H_n}{n} = 0$ where $H_n$ is the nth Harmonic number $= \sum_{i=1}^{n} \frac{1}{...

Q: Harmonic number divided by n

AnneHow do I prove that $\dfrac{H_n}{n}$ (where $H_n$ is a harmonic number) converges to $0$, as $n \to \infty$?

Q: Find $\lim_{n\to\infty} (1+\frac{1}{2}+...+\frac{1}{n})\frac{1}{n}$

Badshah Find the following limit: $$\lim_{n\to\infty} \left(1+\frac{1}{2}+...+\frac{1}{n}\right)\frac{1}{n}$$ My intuition says that this goes to zero, because $1/n$ goes much faster to zero than the harmonic series go to infinity, but how can I prove this?

(I have answered one of them before looking for duplicates. Maybe I should have searched first - it is a kind of question which is very likely to have been asked before. On the other hand, the other answers probably did not look for them either.)

One of the older posts only had two answers, so I voted to close it as a duplicate of today's post. (It has more answers.)
One of the posts seems mostly like the OP wants to ask about their own attempts.
I cannot decide between the remaining two posts. Having posted answer to one of them, I am probably not unbiased.
