The following data was taken from a recent TD Ameritrade screen for treasury bills for an investor looking to invest $5,000:

	Price	YTM
1 week out	99.963	2.20%
2 weeks out	99.896	2.88%
3 weeks out	99.816	3.31%
4 weeks out	99.748	3.36%

Assuming the pure expectations theory holds with these rates, what does this mean for expected weekly rates investors can expect to receive during future weeks?
