#+2#

Explanation:

Oxygen always has an oxidation number of #-2# unless in peroxides, like #H_2O_2#, where it has an oxidation of #-1#.

When #O# is attached to an even more electronegative element (#F#), it has a positive oxidation number.

You can also check this because #F# normally has an oxidation of #-1# in its compounds, so

#(O)+2(F)=0#

#(+2)+2(-1)=0#
