将公式放在一个块的下方

我希望下面幻灯片中的公式$2 \leq i \leq n$和$2 \leq i \leq n$, \hspace{5mm}, $n-i+3 \leq k \leq n$从同一点开始，这样它们就位于块的正下方。我尝试了几种方法，但似乎都没有用。

\begin{frame}[t]{Chain Ladder}
\begin{itemize}
\item relies on the assumption that expectations underlying columns and rows are      proportionalè
\setbeamercolor{block title}{use=structure,fg=white,bg=purple!75!black}
\setbeamercolor{block body}{use=structure,fg=black,bg=black!20!white}
\begin{block}{developmentfactor}
$\hat{f_j} = \frac{\sum\limits_{i=1}^{n-j+1} C_{ij}}{\sum\limits_{i=1}^{n-j+1}   C_{i,j-1}}$ \hspace{30mm} $2 \leq j \leq n$
\end{block}
\setbeamercolor{block title}{use=structure,fg=white,bg=purple!75!black}
\setbeamercolor{block body}{use=structure,fg=black,bg=black!20!white}
\vspace{5mm}
\item development factors applied to latest cumulative claim give forecasted future   value of cumulative claims
\begin{block}{estimated cumulative claim}
$\hat{C_{i,n-i+2}} = C_{i,n-i+1} \hat{f_{n-i+2}}$ \hspace{15mm} $2 \leq i \leq n$ \\ 
$\hat{C_{i,k}} = \hat{C_{i,k-1}} \hat{f_k}$ \hspace{15mm} $2 \leq i \leq n$,         \hspace{5mm}, $n-i+3 \leq k \leq n$

\end{block}
\end{itemize}
\end{frame}

也许你只是将​​其作为表格材料插入。像这样，你也可以将第二个块的内容与第一个块的内容对齐：

% arara: pdflatex

\documentclass{beamer} 
\usepackage{array}
\setbeamercolor{block title}{use=structure,fg=white,bg=purple!75!black}
\setbeamercolor{block body}{use=structure,fg=black,bg=black!20!white}

\begin{document}    
\begin{frame}[t]{Chain Ladder}
    \begin{itemize}
        \item relies on the assumption that expectations underlying columns and rows are proportionalè
        \begin{block}{development factor}
            \begin{tabular}{@{}>{$}p{5cm}<{$}>{$}l<{$}}
                \hat{f}_j = \frac{\sum\limits_{i=1}^{n-j+1} C_{ij}}{\sum\limits_{i=1}^{n-j+1}   C_{i,j-1}} &2 \leq j \leq n
            \end{tabular}   
        \end{block}     
        \baselineskip5mm
        \item development factors applied to latest cumulative claim give forecasted future value of cumulative claims
        \begin{block}{estimated cumulative claim}
            \begin{tabular}{@{}>{$}p{5cm}<{$}>{$}l<{$}}
                \hat{C}_{i,n-i+2} = C_{i,n-i+1} \hat{f}_{n-i+2} \hspace{15mm} &2 \leq i \leq n \\ 
                \hat{C}_{i,k} = \hat{C}_{i,k-1} \hat{f}_k &2 \leq i \leq n, \quad, n-i+3 \leq k \leq n
            \end{tabular}
        \end{block}
    \end{itemize}
\end{frame} 
\end{document}
