@thomas111121 what is the original question and what calculator do you use? i wouldn’t algebraically solve the equation since it would be time consuming. i would use the TVM function on your calculator. based on the info you posted N=3, PV=102.96, FV=100, PMT=5, compute I/Y. you can also just guess and check based on the answer choices but that would take more time.
hope that helps!

the question is in relation to pricing bonds. Suppose that the one year spot rate is 2%, the 2 year spot rate is 3% and the 3 year spot rate is 4%. Calculate the price of the 3 year bond that makes a 5% annual coupon payment which comes to 102.960. The problem is how do I calculate the YTM? I know you put the 102.960 = 5/(1+r) + 5/(1+r)squared + 105(1+r) cubed to work it out but I don’t know how to compute it. I have a texas B11 Plus professional

so in this case you actually don’t need the spot rates the question provides you with (you would plug in the spot rates to calculate the PV of the bond using the arbitrage free valuation approach.) you have the right formula listed above to calculate YTM, but you actually don’t need to go through all of that math since you can just use the time value of money function on your calculator (its the thirds row down from the top of the calculator). the question gives you the present value (102.96), future value (100), coupon payment (5% * 100) and periods to maturity (3) using these inputs you can press the CPT (compute) I/Y to get the yield to maturity. this will solve for r in the formula you posted above above
to use the TVM function your going to input the number first and then press the respective button (input102.96, press PV, input 3 press N)
hope this cleared things up a bit! if not ask away and i can try to clarify or someone else may be able to help 🙂
