Arrangement Sequence Analysis

The question presents a sequence of characters and requires us to identify the unique pattern among the given groups based on their positions. We need to find the group that does not fit the common positional relationship observed in the other groups.

Mapping Elements to Positions

To solve this, we first establish the position of each element in the given arrangement. Let's list the arrangement and assign numerical positions starting from 1:

Evaluating Group Patterns Based on Positions

We will now examine each option by identifying the positions of its constituent characters and analyzing the differences between these positions to find a consistent pattern.

Option 1: E & G

• The character E is at position 2.
• The character & is at position 4.
• The character G is at position 6.
• The sequence of positions is 2, 4, 6.
• The difference between consecutive positions is $4 - 2 = 2$ and $6 - 4 = 2$.
• This sequence follows a pattern of increasing by +2.

Option 2: 2 B #

• The character 2 is at position 18.
• The character B is at position 20.
• The character # is at position 22.
• The sequence of positions is 18, 20, 22.
• The difference between consecutive positions is $20 - 18 = 2$ and $22 - 20 = 2$.
• This sequence also follows a pattern of increasing by +2.

Option 3: C 3 @

• The character C is at position 23.
• The character 3 is at position 21.
• The character @ is at position 19.
• The sequence of positions is 23, 21, 19.
• The difference between consecutive positions is $21 - 23 = -2$ and $19 - 21 = -2$.
• This sequence follows a pattern of decreasing by -2.

Option 4: F H a

• The character F is at position 5.
• The character H is at position 7.
• The character a is at position 9.
• The sequence of positions is 5, 7, 9.
• The difference between consecutive positions is $7 - 5 = 2$ and $9 - 7 = 2$.
• This sequence follows a pattern of increasing by +2.

Option 5: M W Z

• The character M is at position 30.
• The character W is at position 32.
• The character Z is at position 34.
• The sequence of positions is 30, 32, 34.
• The difference between consecutive positions is $32 - 30 = 2$ and $34 - 32 = 2$.
• This sequence follows a pattern of increasing by +2.

Identifying the Outlier

By comparing the patterns identified across all options, we can see that four of the options (1, 2, 4, and 5) exhibit a consistent positional pattern where the positions increase sequentially with a difference of +2. Option 3, however, shows a descending positional pattern with a difference of -2.

Conclusion

The group that does not belong to the established pattern is C 3 @. This is because its elements' positions (23, 21, 19) form a decreasing sequence, unlike the ascending sequences formed by the positions of elements in the other groups (E & G: 2, 4, 6; 2 B #: 18, 20, 22; F H a: 5, 7, 9; M W Z: 30, 32, 34).
