A two-word instruction is stored in memory at an address designated by the symbol A. The address field of the instruction (stored at A + 1) is designated by the symbol Y. The operand used during the execution of the instruction is stored at an address symbolized by EA. An index register contains the value X. With the help of diagram, state how EA is calculated from the other addresses if the addressing mode of the instruction is (1)- direct (2)- indirect (3)- indexed (4)-Relative (5)- Register indirect
