$$K_a:6.3\times 10^{-5}3.3\times 10^{-5}8.2\times 10^{-5}1.75\times 10^{-5}$$ $-{\mathrm{OCH}}_3$ group displays electron withdrawing acid strengthening inductive effect at the meta position but at the para position, an electron releasing acid weakening resonance effect operates (which at this position outweighs the inductive effect).
