The sequences $(a_n)$ and $(g_n)$ satisfy $a_n{g}_n$ for all $n1,$ and converge to the same limit which we write as AGM$(x,y)$ and call the arithmetic$-$geometric mean of $x$ and $y.$ the sequences $(a_n)$ and $(g_n)$ defined above, and returning the first value of $a_n$ such that and your function must work for all such values of $x$ and $y.$
