In determining oxidation numbers, Oxygen is always a -2. Here there are two of them, so the total is -4. Since this is a neutral compound, the total oxidation numbers must add up to zero, so the oxidation number of Pb must be +4, to balance out the -4 provided by oxygen. Remember that each oxygen by itself is -2, only the total of both is -4.
