Assume that the Pure Expectation Theory determines interest rates in the markets. Today's market rates for different maturities are as follows:

1 year = 3.7%

2 years = 4.9%

3 years = 5.3%

4 years = 6.7%

5 years = 7.4%

What is the implied 2 year interest rate for investing in 3 years?

Enter your answer as a percentage, without the percentage sign ('%'), and rounded to 1 decimal. For example. if your answer is 7.2134%, just enter 7.2
