When they say “End of year 1” they mean “End of 1 year from now”. So you are correct, they should get the values of payments at t=3,4,5. And they are correct, those are the payments they are...

You want v^2 either way, because you want the value 2 years before the annuity starts, not the value 2 years before the first payment. Jeff buys a_{\overline{n}|}, so its value 2 years earlier is...

A very common version of the important relationship is a doubledot angle n = (1+l) a angle n. That extends to a doubledot 300 times v^60 = a 300 times v ^ 59. You should consider using...

No. Different angles mean different number of payments. 301 payments in the first, only 300 in the second. As to timing, a angle 301 is payments (measured from the start of the annuity) at 1, so...

Consider this very similar question If the question were phrased that way, I think you would surely apply an s at 5% to those payments. If that is how much the company is paying, the formula gives...

I agree with the thinking behind I, in that the term structure of interest rates is the same throughout, so that anything invested for 1 year will earn 5% for that year, whenever invested. That...

They could have treated it as a 10 year annuity, multiplying by 1200. It should give the same answer as a 120 month annuity of 100. You say “we have to convert nominal interest rate to annual...

In s|19, payments are invested at the end of each period, so nothing has earned 19 periods interest and 1 payment has received 0 periods interest.

You were correct when you wrote the terms, starting with 1000+300=1300. Your formula would start with 1000 (in the level annuity)+150 (in the decreasing annuity), total only 1150.
