Problem $6-17$ Forecasting Interest Rates $($LG$6-8)$

You note the following yield curve in The Wall Street Journal. According to the unbiased expectations theory,

what is the $1-$year forward rate for the period beginning one year from today, $2f_1?$

Note: Do not round intermediate calculations. Round your percentage answer to $2$ decimal places $($i$.$e$.,$

$0\mathrm{.}1234$ should be entered as $12\mathrm{.}34).$ Please show me the correct way to solve this on Excel.
