Manganese (VI) is not stable in acidic medium and undergoes disproportionation reaction.

The reaction is given below:

\\\mathrm{3MnO_{4}^{2-}+4H^{+}\longrightarrow 2MnO_{4}^{-}+MnO_{2}+2H_{2}O}\\\mathrm{(VI)}\; \; \; \; \; \; \; \; \; \; \; \; \; \; \; \; \; \; \; \; \; \; \; \; \; \; \; \mathrm{(VII)}\; \; \; \; \; \; \; \mathrm{(IV)}

The difference in oxidation state of two lons

=7-4=3

Hence, the answer is 3
