$$\actsymb{}{}{A}{}{\overset{1}{x}:\angl{n}}=\frac{M_{x}-M_{x+n}}{D_{x}}$$<br />
$n$ 年期的期初生存年金的换算函数为：<br />
$$\actsymb{}{}{\ddot{a}}{}{x:\angl{n}}=\frac{N_{x}-N_{x+n}}{D_{x}}$$<br />
（1）首先列式：<br />
$$P\actsymb{}{}{\ddot{a}}{}{30:\angl{20}}=P\frac{N_{30}-N_{50}}{D_{30}}=20000\actsymb{}{}{A}{}{\overset{1}{30}:\angl{20}}=20000\frac{M_{30}-M_{50}}{D_{30}}$$<br />
所以：<br />
$$P=20000\frac{M_{30}-M_{50}}{N_{30}-N_{50}}$$<br />
（2）在UDD假设下：<br />
$$\actsymb{}{}{\ddot{a}}{(m)}{\endowxn}=\frac{id}{i^{(m)}d^{(m)}}\actsymb{}{}{\ddot{a}}{}{x:\angl{n}}-\frac{i-i^{(m)}}{i^{(m)}d^{(m)}}(1-\Ex{n}{x})$$</p>
<p dir="auto">其中：<br />
$$\Ex{n}{x}=\frac{D_{x+n}}{D_{x}}$$</p>
<p dir="auto">列式：<br />
$$12P\actsymb{}{}{\ddot{a}}{(12)}{\endow{30}{10}}=20000\actsymb{}{}{A}{}{\overset{1}{30}:\angl{20}}$$</p>
<p dir="auto">全部代入算出P即可。</p>
