J, S, B, K, ?
Identifying the Letter Series Pattern
The question presents a letter series: J, S, B, K, ?. We need to find the pattern to determine the missing letter.
Analyzing the Alphabetical Positions
First, let's convert the letters to their corresponding positions in the English alphabet:
- J is the 10th letter.
- S is the 19th letter.
- B is the 2nd letter.
- K is the 11th letter.
Determining the Pattern Rule
Let's examine the difference between the positions of consecutive letters. We'll consider the alphabet as a cycle (A=1, ..., Z=26).
- From J (10) to S (19): The difference is $19 - 10 = +9$.
- From S (19) to B (2): Moving forward, $19 + 9 = 28$. Since there are 26 letters, we wrap around: $28 \pmod{26} = 2$. The 2nd letter is B. The difference is $+9$.
- From B (2) to K (11): The difference is $11 - 2 = +9$.
The consistent pattern is adding 9 to the alphabetical position of the current letter to get the position of the next letter, with wrap-around.
Calculating the Missing Letter
To find the letter that replaces the question mark, we apply the pattern to the last known letter, K (11):
- Current letter: K (position 11)
- Apply the pattern: $11 + 9 = 20$.
- The 20th letter of the alphabet is T.
Conclusion
Therefore, the letter T replaces the question mark to complete the series.
