O 8 F # 4 @ M 2 E Q % R T & 6 Z * N S $ 7 A 

Step 1: If a symbol is immediately preceded and followed by a letter then write it between 6 and Z. 

Step 2: If a number is immediately preceded by a symbol and immediately followed by a letter then write it between M and 2.

Note: Step 2 is performed after completion of step 1.
1
With respect to the sequence after step 2, four of the following five are alike in some way and thus form a group. Which of the following does not belong to the group?
» Explain it
E
From the following explanation it is clear that '6*T' is the odd one out because 'T' is not third to the left of 6 in the sequence after step 2.

Logic: Second element is second to the right of first element; third element is third to the left of first element.

Hence option E is correct.

Sequence after step 1:

O 8 F # 4 @ M 2 E Q R T & 6 % * Z N S $ 7 A
