Abstract
For the function $\tau \left( {1,1,2;n} \right)$ that defines the number of different representations of $n$ in the form $n = n_1 n_2 n_3^2 $, we construct an asymptotic formula of its summatory function in arithmetic progression, nontrivial for $q \ll x^{\frac{14}{27}}$, where $q$ is the difference of the progression.
