This is what it gives me for Treasury securities:

Maturity Yield

1 year 6.0%

2 years 6.2%

3 years 6.4%

4 years 6.5%

5 years 6.5%

Question:

Assume that the pure expectations theory of the term structure is correct. What does the market expect will be the interest rate on 2-year securities3 years from now?

I need help learning how to solve it. I am confused as to what the equation is. Please help. Thank you.
