The rule says that the first priority for the lowest numbers is given to the substituent of highest priority, i.e., $CHO$.
The rule says that the first priority for the lowest numbers is given to the substituent of highest priority, i.e., $CHO$.
Here, the other group will be taken as a substituent. The numbering of the other groups will be such that the other groups should be on the least numbering.
Hence, the name $2$-Methoxy-$4$-nitro benzaldehyde.
