Abstract: The paper characterizes the length of maximal sequences satisfying conditions (i) and (ii) of (FC)-sequences, and proves some properties of (FC)-sequences, such as a bound on their lengths. As a consequence we get some results for mixed multiplicities and multiplicities of Rees rings of equimultiple ideals. We also prove that if $I$ is an ideal of positive height and $x_1, x_2, \ldots,x_p$ is an arbitrary maximal sequence in $I$ satisfying conditions (i) and (ii) of (FC)-sequences, then $(x_1,x_2, \ldots, x_p)$ is a reduction of $I.$
