Need help with attached photo.

Suppose that the current 1-year rate (1-year spot rate) and expected 1-year T-bill rates over the following three years (i.e. years 2,3 , and 4, respectively) are as follows: 2R1=2.94%,E(2r1)=4.30%,E(3r1)=4.80%,E(4r1)=6.30% Using the unbiased expectations theory, calculate the current (long-term) rates for one-, two-, three-, and four-year-maturity Treasury securities. (Do not round intermediate calculations. Round your answers to 2 decimal places.)
