  In this paper we consider the recurrent equation
$$\Lambda_{p+1}=\frac1p\sum_{q=1}^pf\bigg(\frac{q}{p+1}\bigg)\Lambda_{q}\Lambda_{p+1-q}$$
for $p\ge 1$ with $f\in C[0,1]$ and $\Lambda_1=y>0$ given. We give conditions
on $f$ that guarantee the existence of $y^{(0)}$ such that the sequence
$\Lambda_p$ with $\Lambda_1=y^{(0)}$ tends to a finite positive limit as $p\to
\infty$.
