Series D3K Pattern Analysis
The question presents a series: D3K, E5J, F7I, G11H, ?. The task is to identify the underlying pattern and determine the missing term.
Letter and Number Sequence Logic
We analyze the pattern by looking at the changes in the first letter, the number, and the last letter separately:
- First Letter Progression: The first letters D, E, F, G are consecutive letters in the English alphabet. Following this pattern, the next letter is H.
- Number Progression: The numbers 3, 5, 7, 11 are consecutive prime numbers. The prime number sequence starts with 2, 3, 5, 7, 11, 13, 17, ... The next prime number after 11 is 13.
- Last Letter Progression: The last letters K, J, I, H are consecutive letters in reverse alphabetical order. The next letter after H in reverse order is G.
Determining the Missing Term
By combining the next elements derived from each sequence:
- Next First Letter: H
- Next Number: 13
- Next Last Letter: G
Combining these results gives the missing term: H13G.
