Q 5 (a) Find the first three terms of the sequence defined by Un = 4un-1, U1 = 5. n+3 1 1 1 (b) (i) Show that (n + 2)(n+3) n +2 1 (ii) Hence find and evaluate (n + 2)(n+3) 72 DO 1 (n + 2)(n+3) n=1 nal (c) (i) Obtain the first three non-zero terms of the Maclaurin series for sin 2x. (ii) Hence find an approximate value for sin() T
