The following sets in the question contain 3 letters. Three of the four sets of letters follow the same order. Find the set in which letters do not follow that order.

Options

A. G, E, C
B. L, J, H
C. R, P, N
D. V, U, R

Answer

To solve the problem, we need to analyze the four sets of letters and determine which one does not follow the same alphabetical order pattern as the others.

### Step-by-Step Solution:

1. **Identify the Sets**: The four sets of letters given are:
- A: G, E, C
- B: L, J, H
- C: R, P, N
- D: V, U, R

2. **Analyze Set A (G, E, C)**:
- The letters in alphabetical order are: C, E, G.
- The difference between C and E is +2 (C → D → E).
- The difference between E and G is +2 (E → F → G).
- So, the pattern for Set A is +2, +2.

3. **Analyze Set B (L, J, H)**:
- The letters in alphabetical order are: H, J, L.
- The difference between H and J is +2 (H → I → J).
- The difference between J and L is +2 (J → K → L).
- So, the pattern for Set B is +2, +2.

4. **Analyze Set C (R, P, N)**:
- The letters in alphabetical order are: N, P, R.
- The difference between N and P is +2 (N → O → P).
- The difference between P and R is +2 (P → Q → R).
- So, the pattern for Set C is +2, +2.

5. **Analyze Set D (V, U, R)**:
- The letters in alphabetical order are: R, U, V.
- The difference between R and U is +3 (R → S → T → U).
- The difference between U and V is +1 (U → V).
- So, the pattern for Set D is +3, +1.

6. **Conclusion**:
- Sets A, B, and C all follow the pattern of +2, +2.
- Set D does not follow this pattern as it has a difference of +3 and +1.
- Therefore, the set that does not follow the same order is **D: V, U, R**.

### Final Answer:
The set in which letters do not follow the same order is **D: V, U, R**.
