If you can only score 3 points or 5 points, What is the largest impossible score?

Question

What is the largest combination of 3 and 5 points you CAN'T make

Answer 1

11? You can't make 1, 2, 4, 7, or 11. Not sure of the theory, but I could make every other number up to 50...My guess is you could make every number above that too.

Answer 2

A zillion point five.

If the score has to be an integer then....7

Answer 3

The largest impossible score?  

Does this "game" go up to a certain score?  Since numbers go on forever, one can generate infinite number of high scores, so there will nver be a highest one.

Answer 4

4?

that would be impossible...

or did you really mean possible?

Answer 5

7

Answer 6

there is no largest number. every number that is not divisible by 3 and 5 is an impossible score.

an example would be 2°n (1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, ... )
