One$-$year Treasury bills currently earn $2\mathrm{.}25$ percent. You expect that one year

from now, $1-$year Treasury bill rates will increase to $2\mathrm{.}75$ percent and that two

years from now, $1-$year Treasury bill rates will increase to $3\mathrm{.}15$ percent. If the

unbiased expectations theory is correct, what should the current rate be on $3-$

year Treasury securities$?($Do not round intermediate calculations. Round

your answer to $2$ decimal places.$)$
