Solution of second order linear homogeneous fuzzy difference equation with constant coefficients by geometric approach

In this article, we have solved an initial valued second order linear homogeneous fuzzy difference equation with constant coefficient using geometric approach. General fuzzy solution structures for the three cases are established depending on the auxiliary roots of the corresponding homogeneous difference equation. Finally, we have taken the numerical examples and solved them using the theoretical results and depicted the graphical scenarios to realize the deviation of the uncertain solution from the exact solution as well as the vagueness of the initial values.
