Question 1 Consider the following cash flow: \begin{tabular}{[cc]} \hline End of year & Amount " \hline 1 & $\$ Q$ \hline 2 & $\$ 2 Q$ \hline 3 & $\$ 3 Q$ \hline$\vdots $ & $\vdots$ \hline $N-1$ & $\$(N-1) Q$ \hline$N$ & $S N Q$ \hline \end{tabular Assuming an annual interest rate of $i \%$, the present value of the cash flow, $P$, can be expressed as: $$ PEQ(P / Q, i \%, N) $$ Show that $$ (P / Q, i %, N)=\left[\frac{(1+i)^{N+1} -(N+1) i-1}{i^{2} (1+i)^{N}} ight] $$ CS.VS. 14317
