In this paper, we study the different formulations of fuzzy difference equation 32971" title="Click to view the MathML source">x_n=wx_n−1+q$x_n=w{x}_{n-1}+q$, where w,q$w,q$ are positive fuzzy numbers. Using a generalization of division for fuzzy numbers, we investigate the existence, uniqueness and global behavior of the solution.
