@SmokeDetector Hrm, a bunch of false positives here.

Someone disagreed with my bot, when the bot claimed that question does not add information to the title "Arithmetic Progression Question". The argument was: it could be something else, like "Arithmetic Progression Intuition" or "Arithmetic Progression Confusion". facepalm

This two questions are a complete mess.

1484173 is closed as a duplicate of 1484140.

However, 1484140 was originally a completely different question. And the answers posted there answer the original version.

So it would be reasonable to rollback 1484140, so that the question and matches the posted answer.

However, then 1484173 is no longer duplicate.

To add a bit more to the confusion, I have edited 1484140 not noticing that it is on hold (not closed as a duplicate). As the first edit after putting on hold, it put this questions into reopen review queue. Which means that if the OP edits and improves the question, it will not be reviewed. (However, I this is not very likely to happen, considering the quality of the question.)

I still think that the cleanest solution would be to rollback. (Since the question was changed after the answers were posted.) And I am not sure what to do about duplicate.

It is probably wasted effort, since the posts are very probably going to be deleted eventually.

I might the rollback. Feel free to change it, if you think that it was not a good decision.

I did not do anything about the question which is no longer a duplicate.

@MartinSleziak Rolling back was right. I have reopened 1484173, will probably close it as duplicate of another question soon, but need to look for the best target.

Didn't find anything better than you linked, so I took that.

Thanks for the response and also for changing the duplicate target.

I searched a bit, too, but did not find a better choice.

I'd guess that among the questions tagged trigonometry+summation we could find a few duplicates. But it is a work for another day, when I have more time.

Yes, there are probably several duplicates. But indeed, finding one needs time and search-fu.

@SmokeDetector Sorry about the stupid pattern, I killed that one now.

The Close Queue is typically above 150 now... and I see questions there that aren't that bad.

Some closeflaggers got overzealous, I think.
