Question

What will come next in the
 following series ?
 ZB, YD, XF, WH, VJ, UL, TN, .....

Accepted Answer

To determine the next element in the series ZB, YD, XF, WH, VJ, UL, TN, we need to analyze the pattern in both the letters and their positions in the alphabet.

1. **Pattern Analysis:**

- **First Letter Sequence:**
     - Z (26th letter), Y (25th letter), X (24th letter), W (23rd letter), V (22nd letter), U (21st letter), T (20th letter)
     - The first letters are decreasing by 1 in each step.

- **Second Letter Sequence:**
     - B (2nd letter), D (4th letter), F (6th letter), H (8th letter), J (10th letter), L (12th letter), N (14th letter)
     - The second letters are increasing by 2 in each step.

2. **Predicting the Next Element:**

- **First Letter:**
     - The last first letter in the series is T (20th letter). Following the pattern of decreasing by 1, the next first letter should be S (19th letter).

- **Second Letter:**
     - The last second letter in the series is N (14th letter). Following the pattern of increasing by 2, the next second letter should be P (16th letter).

3. **Conclusion:**

- Combining the predicted first and second letters, the next element in the series should be SP.

4. **Explanation of Options:**

- **Option 1: ST**
     - Incorrect because the second letter T does not follow the pattern of increasing by 2 from N.

- **Option 2: SP**
     - Correct because both the first letter S and the second letter P follow the established patterns of the series.

- **Option 3: UT**
     - Incorrect because the first letter U does not follow the pattern of decreasing by 1 from T, and the second letter T does not follow the pattern of increasing by 2 from N.

- **Option 4: CT**
     - Incorrect because neither the first letter C nor the second letter T follows the established patterns of the series.

Therefore, the correct answer is Option 2: SP, as it logically follows the pattern established in the series.
