Letter Series: Finding the Missing Term

This question involves identifying a pattern in a sequence of letters and determining the next letter that logically follows. We need to analyze the given series: F, P, I, S, L, V, ? to find the missing letter.

Analyzing the Letter Pattern

Letter series questions often contain hidden patterns. Sometimes, these patterns involve skipping letters, moving forward or backward in the alphabet by a certain number of positions, or even alternating between different patterns. Let's examine the given series:

• The series is: F, P, I, S, L, V, ?
• Let's assign numerical positions to each letter based on its place in the alphabet (A=1, B=2, ..., Z=26).
  • F = 6
  • P = 16
  • I = 9
  • S = 19
  • L = 12
  • V = 22

Looking at the series, it appears to be composed of two separate, interleaved patterns:

• Pattern 1 (Odd Positions): The letters at the 1st, 3rd, 5th, and 7th positions: F, I, L, ?
• Pattern 2 (Even Positions): The letters at the 2nd, 4th, and 6th positions: P, S, V

Solving Pattern 1

Let's analyze the sequence F, I, L based on their alphabetical positions:

• F is the 6th letter.
• I is the 9th letter.
• L is the 12th letter.

We can observe the difference in positions between consecutive letters in this pattern:

• Position of I - Position of F = $9 - 6 = 3$
• Position of L - Position of I = $12 - 9 = 3$

The pattern shows a consistent increase of 3 positions in the alphabet for each subsequent letter. To find the next letter (which comes after L in this pattern), we add 3 to the position of L:

• Next Letter Position = Position of L + 3 = $12 + 3 = 15$

The 15th letter of the alphabet is O.

Checking Pattern 2

Let's quickly verify the second pattern to ensure consistency:

• P is the 16th letter.
• S is the 19th letter.
• V is the 22nd letter.

Calculating the differences:

• Position of S - Position of P = $19 - 16 = 3$
• Position of V - Position of S = $22 - 19 = 3$

This pattern also follows a consistent increase of 3 positions. This confirms our understanding of the interleaved structure.

Conclusion

The question mark (?) occupies the 7th position in the series, which corresponds to the first pattern (F, I, L, ?). Based on our analysis, the next letter in this pattern is O.
