Query: Symbolic solutions of some linear recurrences   A symbolic method for solving linear recurrences of combinatorial and
statistical interest is introduced. This method essentially relies on a
representation of polynomial sequences as moments of a symbol that looks as the
framework of a random variable with no reference to any probability space. We
give several examples of applications and state an explicit form for the class
of linear recurrences involving Sheffer sequences satisfying a special initial
condition. The results here presented can be easily implemented in a symbolic
software.
