A pseudorandom sequence of numbers is one that appears to be statistically random, despite having been produced by a completely deterministic and repeatable process.

<programming> One of a sequence of numbers generated by some
algorithm so as to have an even distribution over some range
of values and minimal correlation between successive
values.
Pseudorandom numbers are used in simulation and
encryption. They are pseudorandom not random because the
sequence eventually repeats exactly and is entirely determined
by the initial conditions.
One of the simplest algorithms is
x[i+1 ] = (a * x[i ] + c) mod m
but this repeats after at most m numbers and successive
numbers are closely related. Better algorithms generally use
more previous numbers to calculate the next number.

Pseudorandom generators
In theoretical computer science and cryptography, a pseudorandom generator (PRG) for a class of statistical tests is a deterministic procedure that maps a random seed to a longer pseudorandom string such that no statistical test in the class can distinguish between the output of the generator and the uniform distribution. The random seed itself is typically a short binary string drawn from the uniform distribution.
