I see a lot of questions like:
What is the next term in the sequence 20,5,3,6,7,12, ... ?
I think they are asked daily. They are generally closed, but can't we do anything to reduce the number of questions asked in this manner? Furthermore, I think it would be good to point out that the question can be asked on Puzzling. SE.
I see three solutions:
Problem: People who have a mathematical question about finding the next term in an arithmetic, geometric or harmonic progression might think that the question is off-topic.
Perhaps better than the first one: Note in the excerpt that it is for sequences and series related to calculus. Although I'm not sure that is the only thing the tag should be used for.
Adding a migration path to Puzzling.SE, so that question can be migrated there more easily.
Problem: Puzzling.SE is currently in beta, so I'm not sure if it is even allowed.
Please discuss whether we should do anything about this.
