Advanced differential equations can be used to simulate many processes in sciencein which evolution rate depends not only on the present, but also on the future. Theappearance of advanced variables can reflect the influence of future factors, so itis very friendly to the decision-making processes. For instance, economic problems,mechanical control engineering and demographic dynamics are possible areas affectedby future factors, see [4].Differential equations with delay and advanced arguments occur in many appliedproblems, especially in mathematical economics, see [5,6].The oscillation theory of differential equations with deviating arguments is studiedfor the first time in document [7]. A developed theory has been formed on the oscillationof delay equations, see [8–10]. A few results have considered equations with advancedarguments, see [11–13]. In addition, for mixed differential equations with delay andadvanced arguments (MDE), the oscillation theory is much less developed, see recentliterature [14–16].In 2016, Agarwal et al. [17] investigated
