a) Find the accumulated value of \$1 at the end of n periods where the effective rate of interest for the k th period, k=1,2,...n, is defined by
i_{k}=(1+r)^{k^{2}}(1+i)-1
b)Show that the answer to a) can be written in the form (1+j)^{n}. Find j.
Ans:
a) a(n)=(1+r)^{\frac{1}{6}(n)(n+1)(2n+1)}(1+i)^{n}
b) j=(1+r)^{\frac{1}{6}(n+1)(2n+1)}(1+i)-1
