2. The arithmetic geometric mean of two positive numbers z,y, denot ed M(r,y) (or agn(z, y)) can be computed iteratively as follows. Initially, a + y) and 91-vry (i.e. the normal arithmetic and geometric means). Then, compute The two sequences will converge to the same number which is the arithmetic- geometrie mean of z, y. Obviously we cannot compute an infinite sequence, so we compute until lan-gal
