The paper considers the boundedness character of positive solutions of the difference equation , , where , , and are positive real numbers. It is shown that (a) If , or , , then this equation has positive unbounded solutions; (b) if , or , , then all positive solutions of the equation are bounded. Also, an analogous result is proved
regarding positive solutions of the max type difference equation , where , , .
