See first of all, all u need is 2 write the electronic configuration of N and O and then proceed by it.  So NO+ consists of 14 electrons (14 electron system) so the molecular orbital configuration of NO+ ion will be.........
               σ1s σ*1s σ2s σ*2s π2pz σ2px π*2py π*2pz σ*2px  and this is the order of energies for NO+ and also elements like NO N2+ CO CO+ etc and the bond order of NO+ will be 3 and it is calculated by 1/2(no of bonding molecular orbitals-no of anti bonding molecular orbitals.
electronic configuration is not mentioned in ur answer,plz update.
