Actually, those are probably NOT the intended answers.

However, they are answers which are as good as any others, including the intended answers.

The point is that, without any instructions as to what kind of sequences these are supposed to be, you can put ANY number next in each sequence and it will be a valid answer.

The only way to know the "right" answer is to ask the person who wrote the problem.

And there is no mathematics in that; so we can't help you.
