    Sorry for not replying. So common difference meaning through addition and subtraction only? Or is multiplication and division possible for it? I can see it's simply the last term*2. So does that make it an arithmetic sequence? The lesson was a bit foggy on this.

    So I guess it's only an arithmetic sequence if the difference is through addition or subtraction, and it is only a pattern or sequence if it's through multiplication or division.
