Is the sequence: $\underbrace{2,2,...2}_{1000\text{times}}$ a harmonic sequence? First of all let me give a bit introduction about what is a harmonic sequence. For e.g.: We can say that $1,\frac{1}{2},\frac{1}{3},...\frac{1}{n}$ is a harmonic sequence because if we take the reciprocal of each ter...

In mathematics, a harmonic progression (or harmonic sequence) is a progression formed by taking the reciprocals of an arithmetic progression. Equivalently, a sequence is a harmonic progression when each term is the harmonic mean of the neighboring terms. As a third equivalent characterization, it is an infinite sequence of the form 1 a , 1 a + d ,...

There is a bug due to which the synonyms of deleted tags are not deleted from the Tags list even though the parent tag is deleted.

I recently encountered this question on MSO, where a user asks about why certain tags appear in the tag overview page. This issue is caused by a synonym that redirects users to a non-existent tag. I've created this SEDE query, and on Stack Overflow alone, a total of 60 approved synonyms exist t...

I am not really sure to which extent one should consider this important - but still, it feels weird that the tag remains on the site despite having no question.
This is what I get now:

@XanderHenderson Should I raise this on meta?
Or is it enough that I have mentioned this is chat? (And you might discuss at some point with other moderator what - if anything - to do about this.)

@MartinSleziak Please bring it up on meta. I'm not really sure what to do in this case (I believe that it will involve staff intervention to fix the problem), and I am in the middle of finals week right now, and on break for the three weeks after.

@XanderHenderson Thanks for the response! I posted a question on meta: Remove the empty tag (geometric-cyclicity). (The feed should post it into this room shortly.)
Good luck with the finals!

Typically, the tags with no questions are automatically removed by a script which runs once a day, this process is called tag pruning. However, there is a known bug which causes that if both tags in a tag synonym have zero question, they cannot be removed by this script. See this bug-report: Auto...

After consulting with other moderators, it seems that removing the link between the two tags should allow the tags to be deleted. I have, therefore, un-synonymized the two tags. They should both be removed at the next cleanup. I have also marked this post status-review, in order to bring the bug in the tag system to the attention of staff. — Xander Henderson ♦ 53 secs ago
Now the tag is no longer shown when searching:
Unless there are some other issues related to orphaned tag synonyms, perhaps this could be considered resolved?

How to solve the equation: $(2x)^{x}=14+x^{x}$ ? I am trying to solve this equation in this way: $(2x)^{x}=14+x^{x}\implies 2^{x}x^{x}=14+x^{x}\implies x^{x}(2^{x}-1)=14\implies x^{x}=\frac{14}{2^{x}-1}\implies x\ln(x)=\ln(\frac{14}{2^{x}-1})\implies W(x\ln(x))=W(\ln(\frac{14}{2^{x}-1}))$. Now he...
