Suppose that the current one$-$year rate $($one$-$year spot rate$)$ and expected one$-$year T$-$bill rates over the following three years

$($i$.$e$.,$ years $2,3,$ and $4,$ respectively$)$ are as follows:

${?}_1{R}_1=0\mathrm{.}4\%,E{(}_2{r}_1)=1\mathrm{.}4\%,E{(}_3{r}_1)=8\mathrm{.}8\%,E{(}_4{r}_1)=9\mathrm{.}15\%$

Using the unbiased expectations theory, calculate the current $($long$-$term$)$ rates for one$-,$ two$-,$ three$-,$ and four$-$year$-$maturity
