    In my somewhat limited opinion, it could be 14 - 3=(11) and (5). Since 28-3=25 followed 5 and 21-3=18 followed by 5; this 14-3=11 followed once again by 5.

    11, 5, then 7 (I know it's an extra term.)

    I think it goes 28-3=25, 5 is a constant, then 28-7=21, and back to 21-3=18

    11, 5, 7, 4, 5, 0, -3, 5, -7, -10, 5,....

    every third term is 5.  the other terms are a multiple of 7 followed by 3 less than it.  then it goes down the list of multiples of 7.
