Question

In the following letter series, some of the letters are missing which are given in that order as one of the alternatives. Choose the correct alternative: \[ a\_bcd\_d\_ab\_ccda\_b\_cda. \]

• A. abcda
• B. adcba
• C. abcdd
• D. adcbb

Hint:

Look for patterns in the series where parts repeat or follow a consistent pattern to identify the missing letters.

Answer 1

The Correct Option is D

We are given the series: \[ a\_bcd\_d\_ab\_ccda\_b\_cda. \] Let's break this down step by step to identify the missing letters. Step 1: Identify the pattern Look at the series carefully: The first and last parts of the sequence seem to be repeating at intervals, with parts of the sequence having gaps.
The pattern seems to follow this:
The first and last letters have repeating sequences in the positions, but there are gaps that we need to fill logically.
Step 2: Fill in the gaps Let's try filling the gaps based on the pattern of alternating letters:
The first position seems to start with \( a \) and then repeats in the series after the gaps.
Similarly, the last letter positions follow a similar pattern.
The correct missing term, based on the observed pattern, is \( \boxed{adcbb} \). Thus, the correct answer is (4) adcbb.
