D, I, N, S, ?
Letter Series Pattern D, I, N, S, ?
The objective is to identify the next letter in the given alphabetical series: D, I, N, S, ?.
We analyze the relationship between consecutive letters to find the pattern.
Alphabetical Position Analysis
First, note the position of each letter in the standard English alphabet:
- D is the 4th letter.
- I is the 9th letter.
- N is the 14th letter.
- S is the 19th letter.
Calculating Series Increment
Calculate the difference between the positions of successive letters:
- The gap between I (9) and D (4) is $9 - 4 = 5$.
- The gap between N (14) and I (9) is $14 - 9 = 5$.
- The gap between S (19) and N (14) is $19 - 14 = 5$.
The pattern reveals a constant increase of 5 positions between each letter in the series.
Determining Missing Letter X
Apply the observed pattern to find the position of the missing letter. Add 5 to the position of the last known letter (S):
- Position of the next letter = Position of S + 5
- Position of the next letter = $19 + 5 = 24$
The 24th letter in the alphabet is X.
Final Answer Verification
The letter X follows the established pattern of adding 5 to the alphabetical position of the preceding letter.
