Pattern #1: (I think it should have started with 7, not 17)

7 -> 14 either added 7 or multiplied by 2

14 -> 8 subracted 6

8 -> 16 either added 8 or multplied by 2

16 -> 10 subtracted 6

10 -> 20 added 10 or multiplied by 2.

The pattern seems to be multiply by 2, then subtract 6, repeat.

14 -> 28

28 -> 22

Pattern #2:

11 -> 13 added 2

13 -> 16 added 3

16 -> 20 added 4

20 -> 25 added 5

25 -> 31 added 6

31 -> 38 added 7

to finish...

38 + 8 = 46

46 + 9 = 55
