Out of all "possible" final scores (0<R<3*n) for a team, participating in N games, how many final results cannot be achieved?

my intention 

Jer is right.
The answer is 1.
For N games the only unachievable score is 3N1.
I have somehow misread Jer's answer.
If one gets in each of his meetings with Grandma
either 1,3 or none candies , there is no way to end up with
3*n1 candies after the nth meeting.
