2. The arithmetic-geometric mean of two positive numbers z, y, denoted M(r,y) (or agm(x, y)) can be computed iteratively as follows. Initially, av) and g1 Vry (i.e. the normal arithmetic and geometric means). Then, compute In+1 Vangn The two sequences will converge to the same number which is the arithmetic- geometric mean of r, y. Obviously we cannot compute an infinite sequence, so we compute until an gul
