Answer: Treasury note yield is 2.52%
Explanation: The equation is : bond yield = rea risk - free rate + average inflation + maturity risk premium
The number of years of maturity , t is 7 since it is a 7 year treasury note.
maturity risk premium = 0.05 * (t-1)% = 0.05 *(7-1)% = 0.3%
the inflation rate is given for the current year and next year and therafter(7 years - 2 years = 5years),it is a consatnt rate.
Average inflation over life of bond =(3.45%+4.75%+2.1%*5)/7 = 2.63%
Treasury note yield = 2.45% +2.63% + 0.3%
Treasury note yield = 2.52%
