How to make a generator?

i have a set of cards that i was wondering if it was possible to find the pattern between them in which i could then just type the first number and the second number would be produced by the generator. is this possible?

first number 2nd "answer" number
1102402845 78198291
1102401766 69455192
1102394128 95515252
1102407498 34131658

WTF....?
Windows has a function for a ID generator. It's like 4 string long generated with brackets enclosing. Example: {3434dfdff-342452sd-233423d-43423df}
