Abstract: Methods of analytic number theory, together with the properties of generalized Gauss sums modulo p are used to derive some third order recurrence formulas involving character sums Ak(p) and Tk(p) under certain conditions for an odd prime p. These results can be applied to solving problems regarding the number of solutions to the general diagonal equation.

Key words: character sums, generalized Gauss sums, quadratic residues, recurrence formulas
