can i find the algorithim of a prng by entering previous sequence Is there any software or can i find it manually the algorithm of a prng by entering previous sequences of results. there is 38 possible outcomes and results can repeat.
If the PRNG is a cryptographically secure PRNG, then no. A basic property of CSPRNG is that if you know all the bits of a sequence of outputs except one, then your probability of guessing that one bit is no better than pure chance.

A deterministic CSPRNG operates by having a secret state. Without finding out the secret state, there's no way to guess outputs.

If the PRNG is not cryptographically secure, then it might be possible to reconstruct some outputs knowing others. In fact that possibility is basically the definition of not being cryptographically secure. Realistically, unless the PRNG is extremely bad, it's rather difficult to find the algorithm given only a few outputs, but it might be very easy to find if you manage to guess the algorithm. Maybe it's a common one?
