  For every $k \in \mathbb{N}$ let $f_k:[\frac{1}{k+1}, \frac{1}{k}] \to [0,1]$
be decreasing, linear functions such that $f_k(\frac{1}{k+1}) = 1$ and
$f_k(\frac{1}{k}) = 0$, $k = 1, 2, \dots$. We define iterated function system
(IFS) $S_n$ by limiting the collection of functions $f_k$ to first n, meaning
$S_n = \{f_k \}_{k=1}^n$. Let $J_n$ denote the limit set of $S_n$. Then
$\lim\limits_{n\to \infty} \mathcal{P}_{h_n}(J_n) = 2$, where $h_n$ is the
packing dimension of $J_n$ and $\mathcal{P}_{h_n}$ is the corresponding packing
measure.
