Pseudo random number algorithm

[billyJ]

I'm trying to figure out this little problem. I'm trying to figure out which algorithm is being used.I know the set of numbers is being used to generate the 5 digit number. I believe a Pseudo random number generator algorithm is being used. I know the set of number are being used as the seed, not sure if a,b & c are treated as separate variables or they are concatenated. a,b &c are the input and the 5digit number is the output

a:347 b:851 c:0381 = 86013

a:347 b:547 c:5840 = 54552

a:347 b:258 c:8744 = 49785

a:347 b:852 c:1707 = 39888


Let me know if anyone has any Ideas.

It appears that the algorithm being used is a Linear Congruential Generator (LCG). It takes three values, referred to as 'a', 'b' and 'c', and produces a 5-digit number as output. The formula for the LCG is as follows: x = (ax+b) mod c. The output of the LCG is then the remainder when the result of the equation is divided by c. In the examples you provided, the algorithm is taking the three values of a, b, and c and using them to generate the 5-digit number.
