Consider a perpetual stream of cash flows. The first cash flow is received at date $1$;

this cash flow equals $1\mathrm{.}00.$ Each subsequent date's cash flow is $1\mathrm{.}25\%$ less than the

cash flow at the previous date. The rate of interest equals $5\%.$ What is the present

$($date $0)$ value of this stream of cash flows?
