abstract = {We use Maple's gfun library to study the limit formulae
for a two-term recurrence (iteration) $AG_N$, which in the case $N=2$
specializes to the well-known Arithmetic-Geometric Mean iteration of Gauss.
Our main aim is to independently rediscover and prove the limit formulae
for two classical cases ($N=2,3$) in a completely automated manner
and to open the way for studying the remaining cases ($N>3$).},
