Understanding the Letter Series Completion Question

This question asks us to find the correct sequence of letters to fill in the blanks within a given letter series. The objective is to identify a repeating pattern or a logical rule governing the series and use it to determine the missing letters.

Analyzing the Given Series and Blanks

The letter series provided is:

P_QU_V_T_URVPTQ_R_P_QU_V

Let's analyze the structure of the series:

• The series consists of 24 positions in total.
• There are 8 blanks, indicated by underscores (_).
• The positions of the blanks are at indices 2, 5, 7, 9, 16, 18, 20, and 23 (assuming the first position is index 1).
• The known letters present in the series are P, Q, U, V, T, R.

Identifying the Underlying Pattern

To solve this type of series completion problem, we look for a pattern. Common patterns include repeating blocks of letters, alphabetical sequences, or progressions based on position.

Let's examine the arrangement of the known letters and the placement of the blanks. The letters involved are P, Q, R, T, U, V. Let's hypothesize a repeating block of 6 letters, such as 'PTQURV'.

If 'PTQURV' is the repeating block, the complete sequence of 24 characters would be:

PTQURVPTQURVPTQURVPTQURV

This generated sequence has the correct length (24 characters) corresponding to the total number of positions in the given series structure.

Step-by-Step Solution: Filling the Blanks

Now, we will map the generated sequence 'PTQURVPTQURVPTQURVPTQURV' onto the original series structure that includes the blanks:

Original Structure: P _ Q U _ V _ T _ U R V P T Q _ R _ P _ Q U _ V

Generated Sequence: P T Q U R V P T Q U R V P T Q U R V P T Q U R V

Let's compare the generated sequence with the original structure, position by position, to determine the letters that fill the blanks:

1. Position 1: The character is P. This matches the generated sequence.
2. Position 2: This is the first blank. The generated sequence has T at this position.
3. Position 3: The character is Q. Matches.
4. Position 4: The character is U. Matches.
5. Position 5: This is the second blank. The generated sequence has R at this position.
6. Position 6: The character is V. Matches.
7. Position 7: This is the third blank. The generated sequence has P at this position.
8. Position 8: The character is T. Matches.
9. Position 9: This is the fourth blank. The generated sequence has Q at this position.
10. Positions 10 through 15: The characters are U R V P T Q. These match the generated sequence.
11. Position 16: This is the fifth blank. The generated sequence has U at this position.
12. Position 17: The character is R. Matches.
13. Position 18: This is the sixth blank. The generated sequence has V at this position.
14. Position 19: The character is P. Matches.
15. Position 20: This is the seventh blank. The generated sequence has T at this position.
16. Position 21: The character is Q. Matches.
17. Position 22: The character is U. Matches.
18. Position 23: This is the eighth blank. The generated sequence has R at this position.
19. Position 24: The character is V. Matches.

By successfully mapping the repeating block 'PTQURV' onto the given structure, we can identify the letters needed to complete the series.

Determining the Correct Combination

The letters filling the blanks, in the order they appear, are:

• First Blank (Position 2): T
• Second Blank (Position 5): R
• Third Blank (Position 7): P
• Fourth Blank (Position 9): Q
• Fifth Blank (Position 16): U
• Sixth Blank (Position 18): V
• Seventh Blank (Position 20): T
• Eighth Blank (Position 23): R

Thus, the combination of letters that completes the series is T, R, P, Q, U, V, T, R.
