There is no way to know what the right answer is to any question like this.

Without any context to tell us what kind of sequence this might be, you can put any number you want in there, and it will be a valid sequence. Expanding the definition of a sequence a bit, you could even put something in there that is not a number...

Dear @greenestamps !


Regarding this issue, I am entirely on your side.


When I started as the tutor 2 years ago at this forum,

I wrote the same words and the same phrases trying to explain the same things.


Surely, it is not Math and should not be the subject or the object at this forum.


It is entertainment puzzles, and they are (as I call it) the mix of Alchemy and Astrology.


These people came to the forum not for Math, but for entertainment only.


They find these problems somewhere in other entertainment sites and copy them here in order for to present our solutions somewhere else.


My point is that this forum is not the place for this . . . mmm. .. even don't know how to call it politely.


But there is Edwin, who is, actually, a brilliant tutor in this forum.


He is enthusiast of such problems and find satisfaction by explaining them to these people.


He really knows a lot about sequences, many very unexpected assosiations, analogies . . . 


There is, actually,  the entire website on sequences, where entusiasts can find everything about it.


There is only one mathematical aspect in this subject.
It is the construction of a polynomial which returns the assigned values of the given sequence.


Edwin teaches visitors enthusiastically to this Math, but also teaches them to everything else in the puzzles and sequences of this kind.


So, I explained you how these things are going in this forum.


I think that had it be our common wish, it would be in our power to eliminate this mix of Alchemy and Astrology in this forum.


By saying "common wish" and "common power" I mean all the tutors of the forum, including Edwin, surely/certainly.
