Consider two sequences generated by $$a_{n + 1} = M(a_n, b_n), b_{n + 1} = M'(a_{n + 1}, b_n),$$ where the $a_n$ and $b_n$ are positive and $M$ and $M'$ are means ...

The simple definition of a mean is that of a numeric quantity which represents the center of a collection of numbers. Here the trick lies in defining the exact type of numeric collection, as beyond ...
