(d) Consider the sequences (xn), (yn) defined recursively as follows: Xn+1 = xn2yn, i. ii. n, Yn+1=Yn2xn for n ≥ 1, x1 = 1, y₁ = 2. Calculate x2, y2 and x3, Y3. - Show using induction or otherwise that for any natural number - Xn+Yni = (1+2i)". Hence or otherwise, show that for any natural number n, iii. Zn = (V5)” cos(n arctan2), n = (V5)” sin(n arctan 2).
