Show me the steps of deremine blue and inf is here i need evey I need all the details step by step and inf is here

Motivated by the above studies, we study the dynamics of following higher

where A, B are positive real numbers and the initial conditions are positive
numbers. Additionally, we investigate the boundedness, periodicity, oscillation
behaviours, global asymptotically stability and rate of convergence of related
higi
order difference equations.
Consider the scalar kth-order linear difference equation
