The "random" numbers produced by computers aren't purely random. They are actually pseudo-random, meaning that they are produced by mathematical formulas that simulate randomness.The linear congruential generator takes a seed X0 and generates subsequent pseudo-random numbers using the formula:
Xn+1=(aXn+c) mod m
X1 is the first pseudo-random number generated, X2 is the second, and so on. Let R be the 2000th pseudo-random number generated by the linear congruential generator when X0=42, a=25, c=31, and m=2^20. What are the last three digits of R?

If the question asks for the last digits, you could code and evaluate the recursive formula to get the results.
If you would like a check, you are welcome. The sum of the 3 last digits is 20.
