Consider the following spot interest rates for maturities of one, two, three, and four years.

r₁ = 4.3%         r₂ = 4.9%         r₃ = 5.6%         r₄ = 6.4%

What are the following forward rates, where f_1,k refers to a forward rate for the period beginning in one year and extending for k years?

f_1,1 =     ;     f_1,2 =     ;     f_1,3  =

Use the equation (1 + r₁)(1 + f_{1, k})^k = (1 + r_k+1)^k+1 to solve for f_{1, k}.
