Abstract: Consider the difference Riccati equation f(z+1)=A(z)f(z)+B(z)/C(z)f(z)+D(z), where A, B, C, D are meromorphic functions, we give its solution family with one-parameter

where Q(z) is any constant in C or any periodic meromorphic function with period 1, and f0(z), f1(z), f2(z) are its three distinct meromorphic solutions.

Key words: difference Riccati equation, solution family, order of growth
