\title{One backward Euler-style Thiele step}
\usage{
thiele_backward_step(V_next, P, delta, mu, benefit = 1, h = 1)
}
\arguments{
\item{V_next}{Reserve at time t+h.}

\item{P}{Premium rate.}

\item{delta}{Force of interest.}

\item{mu}{Force of mortality at time t.}

\item{benefit}{Benefit amount. Defaults to 1.}

\item{h}{Step size.}
}
\value{
Numeric vector.
}
\description{
Approximates the reserve at time \eqn{t} from a known reserve at
time \eqn{t+h}.
