### Abstract

The hypergeometric function _{2}F_{1} [a_{1}, a_{2} ; a_{3} ; z] plays an important role in mathematical analysis and its application. Gauss defined two hypergeometric functions to be contiguous if they have the same power-series variable, if two of the parameters are pairwise equal, and if the third pair differs by ±1. He showed that a hypergeometric function and any two other contiguous to it are linearly related. In this paper, we present an interesting formula as a linear relation of three shifted Gauss polynomials in the three parameters a_{1}, a_{2} and a_{3}. More precisely, we obtained a recurrence relation including _{2}F_{1} [a_{1} + α_{1}, a_{2} ; a_{3} ; z], _{2}F_{1} [a_{1}, a_{2} + α_{2} ; a_{3} ; z] and _{2}F_{1} [a_{1}, a_{2} ; a_{3} + α_{3} ; z] for any arbitrary integers α_{1}, α_{2} and α_{3}.
