Tricritical points of layer Ising system consisting of mixed spin-2 and spin-5/2 ferrimagnetic honeycomb lattice layers which are coupled together with two kinds of positive interlayer coupling are examined by the use of the effective-field theory with correlations. In particular, the effects of int
