L'uguaglianza è verificata se la media aritmetico-geometrica $\operatorname {M} (a,b)$ di numeri complessi $a,b$ (tale che $a,b\neq 0;a\neq \pm b$ ) è definita come segue: Siano $a_{0}=a$ , $b_{0}=b$ , $a_{n+1}=(a_{n}+b_{n})/2$ , $b_{n+1}=\pm {\sqrt {a_{n}b_{n}}}$ dove i segni sogno scelti tale che $|a_{n}-b_{n}|\leq |a_{n}+b_{n}|$ per ogni $n\in \mathbb {N}$ . Se $|a_{n}-b_{n}|=|a_{n}+b_{n}|$ , il segno è scelto tale che $\Im (b_{n}/a_{n})>0$ . Allora $\operatorname {M} (a,b)=\lim _{n\to \infty }a_{n}=\lim _{n\to \infty }b_{n}$ . Quando $a,b$ sono positivi reali (with $a\neq b$ ), questa definizione coincide con la solita definizione di media aritmetica-geometrica per numeri reali interi positivi.
