I need help with this problem. I do not understand what it's asking for. Thanks!

3. 1Write down the equation that is used to compute the time t duration of a three year 4.5% coupon bond (with face value equal to 10H) when the yield to maturity for coupon bonds expiring in t+1,t+2 and t+3 are respectively 3%, 4% and 5%. Use the available numbers to indicate precisei}F how you would compute the weights in the duration formula.
