Choose the missing term from the given alternatives that will correctly complete the series ADVENTURE, DVENTURE, DVENTUR, ?, VENTU.

Introduction / Context:

This is a word series question built from the single base word ADVENTURE. Parts of the word are gradually removed in a systematic way to form each subsequent term in the series. Such problems test a candidate ability to track letter removal from the beginning and end of a word and to infer the next logically shortened form. These questions rely more on pattern observation than on complex language knowledge.

Given Data / Assumptions:

• The series is ADVENTURE, DVENTURE, DVENTUR, ?, VENTU.
• All terms are derived from the base word ADVENTURE.
• At each step, one letter appears to be removed from either the start or the end.
• We must find the unique intermediate form that continues this removal pattern.

Concept / Approach:

The key idea is to compare each term with its predecessor and examine which letter has been removed. If we see a consistent alternation between removing the first and the last letter, we can predict the next step. The process is like trimming the word from alternating ends, which produces a nested sequence. Recognizing this alternation helps us determine exactly which letters remain at each stage, including the missing term.

Step-by-Step Solution:

Step 1: Start with ADVENTURE. Step 2: The second term is DVENTURE, which is obtained by removing the first letter A from ADVENTURE. Step 3: The third term is DVENTUR, which is obtained from DVENTURE by removing the last letter E. Step 4: Following the alternation of removing from the front and then from the back, the next step should remove the first letter D from DVENTUR, leaving VENTUR. Step 5: The given last term is VENTU, which is obtained by removing the final letter R from VENTUR, confirming that the pattern continues correctly.

Verification / Alternative check:

List the transformations clearly: ADVENTURE minus first letter A becomes DVENTURE. DVENTURE minus last letter E becomes DVENTUR. DVENTUR minus first letter D becomes VENTUR. VENTUR minus last letter R becomes VENTU. The process is therefore: remove from front, remove from back, remove from front, remove from back, and so on. The missing word between DVENTUR and VENTU must be the form that appears after removing from the front but before removing from the back again, which is VENTUR. This confirms the pattern and the answer.

Why Other Options Are Wrong:

Option VENTURE reintroduces letters that were already removed and breaks the monotonic shrinkage of the word. Option DVENT still begins with D but is shorter than DVENTUR in an incorrect way and does not match the alternating front back removal rule. Option DVENTU also deviate from the simple front or back removal pattern by effectively removing letters from the middle. Option AVENTUR adds the letter A at the front, reversing part of the earlier removal. None of these match the strict alternate trimming rule that the series demonstrates.

Common Pitfalls:

Some students miscount letters or assume multiple letters are removed at each step, leading to complicated interpretations. Others overlook the alternation and think letters are always removed from the same side. Another error is to focus on the meaning of the word rather than on its spelling structure. It is essential to concentrate only on which characters are lost from one term to the next and to track that process consistently across the entire series.

Final Answer:

The missing word that continues the alternation of removing letters from the front and back is VENTUR.
