How to check whether an infinite set is closed under addition?

Given k positive numbers a_1<a_2<a_3<...<a_k, and all integers greater
than a_k, we want to check whether this set {a_1, a_2, a_3,...a_k, a_k
+ 1, a_k+2, ......} is closed under addition.
Is there any easy way to do this? any functions that we could use in
Mathematica or Matlab?
Your help will be greatly appreciated.
