Dear Student,
Here inert pair effect doesnot comes into role. Basicity of metal hydroxides increases as we move down the group. This is because as we move down the group, size of the metal increases which results in weakening of M-OH bond, thereby increasing basicity of hydroxides. Also, the metallic character increases on going down, thus increasing the basicity of metal hydroxides.
