    so because the d value changes, this means we do NOT have a common difference from term to term

    that means we do NOT have an arithmetic sequence

    for it to be arithmetic, you would have to keep adding the same value each time to generate each new term example 1, 7, 13, 19, ... here I'm adding 6 each time
