Explanations:In this question, we are given a sequence of letter groups: AEFG, BHIJ, ..., DNOP. The task is to identify the pattern and determine the missing group. To solve this, we need to analyze the pattern in the given sequence.
First, let's examine the starting letters of each group:
- The first group starts with 'A'.
- The second group starts with 'B'.
- The fourth group starts with 'D'.
We can see that the starting letters are in alphabetical order, with each group starting one letter ahead of the previous group. Therefore, the missing group should start with 'C'.
Next, let's look at the pattern within each group:
- The first group is AEFG.
- The second group is BHIJ.
- The fourth group is DNOP.
We can observe that each group consists of four consecutive letters. The first letter of each group is followed by the next three consecutive letters in the alphabet.
Applying this pattern to the missing group, which starts with 'C', the next three consecutive letters are 'K', 'L', and 'M'. Therefore, the missing group is CKLM.
Let's verify the pattern with the given options:
- Option A: CIJK - This does not follow the pattern because the letters after 'C' are not consecutive.
- Option B: CFGH - This does not follow the pattern because the letters after 'C' are not consecutive.
- Option C: CKLM - This follows the pattern because the letters after 'C' are consecutive.
- Option D: CKMN - This does not follow the pattern because the letters after 'C' are not consecutive.
Thus, the correct answer is CKLM, as it follows the established pattern of starting with the next letter in the alphabet and including the next three consecutive letters.
