Which of the following letter will replace the question mark (?) in the given series? R, O, L, I, F, ?
Letter Series Reasoning
The question asks to find the next letter in the alphabetical series: R, O, L, I, F, ?
Identifying the Pattern
To solve this letter series, we need to identify the pattern between consecutive letters. We can do this by looking at their positions in the English alphabet:
- R is the 18th letter.
- O is the 15th letter.
- L is the 12th letter.
- I is the 9th letter.
- F is the 6th letter.
Calculating the Difference
Let's find the difference between the positions of consecutive letters:
- Position of O - Position of R = $15 - 18 = -3$
- Position of L - Position of O = $12 - 15 = -3$
- Position of I - Position of L = $9 - 12 = -3$
- Position of F - Position of I = $6 - 9 = -3$
The pattern is that each letter's position in the alphabet is 3 less than the previous letter's position.
Determining the Missing Letter
To find the letter that replaces the question mark (?), we apply the same pattern to the last letter, F:
- Position of ? = Position of F - 3
- Position of ? = $6 - 3 = 3$
The 3rd letter in the English alphabet is C.
Therefore, the letter C will replace the question mark in the given series.
