Spot rate vs future rate

Annual continuously compounded spot rates: s1=5%, s2=5.1%, s3=5.2%,

Bond: 1.5 year, Face value=100, semi annual coupon, 6%.

calculate the bond price.

can anyone help with this? thank you~

the below pic is my solution which is incorrect.

Check your exponents; you have the wrong interest rates for periods 2 & 3.

thank you!
