In a certain football contest the winner scores 3 points, the loser 0, and in the case of a draw each team scores 1 point.

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

Rethink.

I will rephrase the question:  ",,.a  certain team, participating in N games

-  how many possible results (number of points) are there?"

hint

zero is one possible result, 1 is, ....3n is ,,,

some numbers cannot be on this list/

end of hint
