The problem with things like this is that any finite sequence of integers

is a pattern. The problem is finding what the setter had in mind, which

means a rule that is simple and obvious when you find it.

I see no simple pattern here, but that does not mean that there is none.

If this is a maths problem then there probably is a simple pattern here.

If this is a puzzle form a non-math web site then the only simplicity may

be in the mind of the setter.

The online encyclopedia of integer sequences does not recognise it, so

if there is a simple pattern it is not a mathematical one.
