*Anionic 14 anuluene is aromatic * but sp2 hybridized anuluene is non aromatic because of which create the steric repulsion of four inner hydrogen.* Another one type of mixed with sp and sp2 hybridized anuluene compound is aromatic. Therefore first you have see which kind of 14 anuluene is present then only you have to decided aromatic, non aromatic.
