Reasoning: Letter Pair Alphabetical Sequence

The goal is to identify the letter pair that does not conform to the pattern established by the other pairs based on their alphabetical positions.

Alphabetical Position Analysis

We assign numerical values to each letter based on its order in the English alphabet (A=1, B=2, ..., Z=26). The pattern is found by examining the relationship between the first and second letters of each pair.

Analyzing the Pairs

Let's calculate the difference between the alphabetical position of the first letter and the second letter for each given pair:

• JG: J is the 10th letter and G is the 7th. The difference is $10 - 7 = 3$.
• VS: V is the 22nd letter and S is the 19th. The difference is $22 - 19 = 3$.
• RO: R is the 18th letter and O is the 15th. The difference is $18 - 15 = 3$.
• FC: F is the 6th letter and C is the 3rd. The difference is $6 - 3 = 3$.

Identifying the Outlier

The pairs JG, VS, RO, and FC consistently show a difference of 3 between the alphabetical positions of their letters (First Letter Position - Second Letter Position). This forms the common group pattern.

Now, we examine the pair MI:

• MI: M is the 13th letter and I is the 9th. The difference is $13 - 9 = 4$.

The difference for MI (4) does not match the common difference of 3 found in the other pairs.

Conclusion

Therefore, the letter pair MI is the one that does not belong to the group, as it deviates from the established alphabetical sequence pattern.
