I am having trouble with this In  Out table... any hints or tips?
IN OUT
1 / 3
3 / 17
10 / 66
6 / 38

things get easier if you arrange the table in order of increasing In values:
1 3 6 10
3 17 38 66
differences:
2 3 4
14 21 28
Note that as the IN difference increases by 1, the OUT difference increases by a multiple of 7
OUT = 3 + 7(IN1)
