Seems extremely basic, but I can't see any relationship, or find it anywhere on the table. The question is:

1.1 Find the value of \(a_\bar{45:n|} \) on A1967–70 mortality at 6% interest.

Numerical Answer given as 10.914.

Hi Dan, there are a few ways to go about this question. One possible way is:

\({a}_\overline{45:20|} \) = \(\ddot{a}_\overline{45:20|} - 1 +v^{20} \cdot _{20}p_{45}\)

you can break it down further (**again all in advance**):

\(\ddot{a}_{45} - v^{20}\ _{20}p_{45}\ddot a_{65} - 1 +v^{20}\ _{20}p_{45}\)

Yeah I did that from first principles, didn't come out right... So it's either the answer that's wrong or I'm not reading the tables correctly. Either way, that clarifies the method, thanks :)
