James,
There are many possibilities, depending on how "tolerant" you want to be with the way your students enter their answer. Here are some examples...
Answer 1: 1, 3, 5, 15
will accept: 1, 3, 5, 15
Answer 2: (1 3 5 15|1,3,5,15|1,3,5 and 15|1, 3, 5 and 15)
will accept:
1 3 5 15
1,3,5,15
1,3,5 and 15*
1, 3, 5 and 15
Answer 3:
(one three five fifteen|one,three,five,fifteen|one,three,five and fifteen|one, three, five and fifteen)
will accept:
one three five fifteen
one,three,five,fifteen*
one,three,five and fifteen*
one, three, five and fifteen
Please note that any extraneous blank space is automatically deleted by the analysis system, which means that all of these answers will be accepted:
1 3 5 15
1 3 5 15
1, 3, 5, 15
However, the following will not be accepted (because the punctuation is not coherent)
1, 3 5, 15
one three, five and fifteen
* personally I would not accept those asterisked responses because they do not follow the punctuation rules of English
