Just need part d

(a) Write down an efficient recurrence relation for an Explain your thought process in words (e.g., using the timeline approach) or prove the result mathematically from first principles. Also write down the initial value for the sequence. (3 marks) (b) Given an effective discrete periodic rate of 4% per period, tabulate the values of an for n=1,2,..., 40. (2 marks) (c) Repeat parts (a) and (b) for (Ia), instead of an (5 marks) (d) Suppose that we would like to develop the relevant calculations for a new actuarial notation defined as (Qa)n = 211 tart. Repeat parts (a) and (b) for (Qa)n instead of (7 marks) = din.
