Decoding the Alphanumeric Series Pattern
The series consists of alphanumeric clusters. We need to find the pattern governing the changes in the first letter, the number, and the last letter from one term to the next.
Analyzing the First Letter Progression
Observe the first letters of the terms: D, G, J.
- D is the 4th letter of the alphabet.
- G is the 7th letter of the alphabet.
- J is the 10th letter of the alphabet.
The pattern is an increase of 3 positions in the alphabet for each subsequent term (4 + 3 = 7, 7 + 3 = 10). Therefore, the next letter will be the 10 + 3 = 13th letter, which is M.
Analyzing the Number Progression
Observe the numbers in the terms: 4, 9, 16.
These numbers are perfect squares:
- $4 = 2^2$
- $9 = 3^2$
- $16 = 4^2$
The pattern is the square of consecutive integers starting from 2. The next number will be $5^2 = 25$.
Analyzing the Last Letter Progression
Observe the last letters of the terms: U, R, O.
- U is the 21st letter of the alphabet.
- R is the 18th letter of the alphabet.
- O is the 15th letter of the alphabet.
The pattern is a decrease of 3 positions in the alphabet for each subsequent term (21 - 3 = 18, 18 - 3 = 15). Therefore, the next letter will be the 15 - 3 = 12th letter, which is L.
Combining the Patterns
Combining the results from the individual patterns:
- First Letter: M
- Number: 25
- Last Letter: L
The alphanumeric cluster that replaces the question mark is M25L.
