Answer:

#+3#

Explanation:

In oxides of elements, oxygen atoms normally have #( -2)# as the value.of the oxidation state.

That means #(-6)# charge comes from #3# oxygen atoms. Since #"Mn"_2"O"_3# is a neutral compound, each #"Mn"# atom should have #(+3)# oxidation value to balance the charge from the oxygen atoms.
