1. Introduction
Te theory of diference equations has grown immensely
overthepastfewdecades.Inthe feldof probability theory,
statistical analysis, combinatorial analysis, electrical net•
works, and sociology, diference equations has emerged as
mathematical models describing real life challenges.
In the recent past, the study of oscillation and non•
oscillation for second order nonlinear diference equations
has garnered a great deal of attention [1, 2]. Te latest re•
search also emphasizes the diferent kinds of diference
equations,includingordinary,linear,nonlinear,superlinear,
quasilinear, sublinear, delay, and neutral delay diference
equations. Interestingly, one can refer the oscillatory be•
havior for sublinear neutral delay second and third order
diference equations in [3, 4]. An investigation of the os•
cillation of the second•order quasilinear neutral delay dif•
ference equations can be seen in [5, 6]. Te study of the
Oscillation of second order half•linear diference equations
has also been given in [7]. Importantly, the oscillation
criteriaforhigherorderneutralequationscanbeseenin[8].
Te literature regarding the present study is referred in
[9, 10]. In a revealing manner, tracking a maneuvering
target, and fault diagnosis of wind turbine gearbox is per•
formed in [11] by using the properties of Riccati diference
equation.In[12],forthestudyoftheMittag•Lefer stability
analysisoffractionaldiscretetimeneuralnetworks,aclassof
semilinear fractional diference equations are used.
A few applications of specifc kinds of nonlinear third

of Mathematics that involve discrete models [13–16].
Moreover,oscillatorysolutionofthirdorderdelaydiference
equations are used to remove speckle noise in the feld of
image processing which can be seen in [17]. Te suitable
smoothingflter fortheedgemaskcomputedusingthethird
order diference equation is examined in [18].
Our main focus in this paper is on the oscillatory be•
haviorofthethird•orderdiferenceequations.Intheearlier
research,plethoraofmethodsabouttheoscillatoryproperty
of third order diference equation were presented. For in•
stance, in [19] the third order diference equation under
consideration is as follows:
