Question 328910: a circular target has scoring regions of 5 and 7 points. what is the largest score that cannot be obtained by throwing any number of darts that land on the target?
Answer by Fombitz(32388)   (Show Source):
You can put this solution on YOUR website! I think you need to re-word your question and bound the number by giving a total number of throws or something like that.
The points that you get are going to be multiples of 5, multiples of 7 or combinations of 5's and 7's.
As an example, possible scores would be 5,10,12,15,17,19,...
If there is no limit on the number of darts, then there is no upper bound on a sum that cannot be reached.
You would then just say a large multiple of 5 plus 1 (500,000,001) or a similarly large multiple of 7 plus 1 (7,000,001).
