can anyone solve this?

Today is 9/30/2020 (September 30, 2020) and today's 1-year spot rate is 0.0119, the 2-year spot rate is 0.0241, the 3-year spot rate is 0.0337, and the 4-year spot rate is 0.0477. Write these down on your answer sheet (you will need them later). According to the pure expectations hypothesis, what is the expected 1-year spot rate for three years from now (i.e., the 1-year rate that is expected to prevail on 9/30/2023)? Your answer should be entered and rounded to the nearest 5 decimal places (e.g., 5.1236% should be entered as 0.05124)
