Pattern or Sequence?

"Pattern" is a vague word without any clear definition; it is used in teaching, to describe a general category of recognition skills. Patterns might exist in sequences; they can also be found in geometry (like patterns on wallpaper, in two or more dimensions) or in logic (patterns of reasoning), and so on. Not all patterns involve repetition, or even mathematics. The Merriam-Webster dictionary defines "pattern", among other things, as a discernible coherent system based on the intended interrelationship of component parts (None of their definitions sounds very mathematical; this is the closest.) "Sequence" is a specific, clearly defined word used in mathematics. A sequence can be considered to be a particular kind of pattern; but in fact a sequence need not have a pattern in any real sense! The mathematical definition of "sequence" in Merriam-Webster is a set of elements ordered so that they can be labeled with the positive integers So all we can really say is that some patterns can be found in sequences; otherwise there is no connection between the words at all!
