The inductive effect is associated with the dipole moment of the compound R-X. If X is at the negative end of a dipole moment, it will draw electrons from the ring and produce -I effect. If X is at the positive end of the dipole moment, it will increase the electron density in the ring and produce +I effect. The +I effect causes all the positions in the ring to be more reactive than un-subtituted benzene, and the -I effect reduces the reactivity at all the position on the ring.

Mesomeric effect - Wikipedia, the free encyclopedia (318 words)
The Mesomeric effect is the effect of the overlap of a p-orbital with the p-orbital on an adjacent atom in the chemical compound to form a delocalised cloud of electrons over both the atoms called a π (pi) bond.
Additionally, the effect of delocalising the electrons and therefore the charge, will reduce the probability of the anion being reprotonated as it is now a "soft nucleophile" (disperse charge) compared to the "hard electrophile" of the proton (small localised charge).
It's important to note that the mesomeric affect as a result of p - orbital overlap has absolutely no affect on the inductive effect, as this effect is purely to do with the electronegativity of the atoms and their structural chemistry (which atoms are connected to which).
