    i'm no to sure where to start with these pattern. If they were in an ordinary descending or ascending order it'd be easier. There's a pattern here, What would be the next number after 20? Can anyone assist please

    3, -6, 12, 4, 20, ?

      For any number you could find a pattern that would make that number the next .
