From Goursat's transformation formulas for the hypergeometric function F (α, β, γ; z), we derive several double sequences given by mean iterations and express their common limits by the hypergeometric function. Our results are analogies of the fact that the arithmeticgeometric mean of 1 and x ∈ (0, 1) can be expressed as the reciprocal of F ( 1 2 , 1 2 , 1; 1 − x 2 ).
