Dictionary Order Explained

To arrange words in the order they appear in an English dictionary, we follow alphabetical rules. This means comparing words letter by letter from the beginning. This method is also called lexicographical ordering.

Given Words:

• 1 vehicle
• 2 verify
• 3 vegan
• 4 venom
• 5 vein

Comparing Words Letter by Letter

Let's examine the words to find their correct dictionary sequence:

1. All the words start with the letter 'v'.
2. The second letter for every word is 'e'. Since the first two letters are the same for all words, we need to look at the third letter to decide the order.

3. We compare the third letters of each word:

   • 3 vegan has 'g'.
   • 1 vehicle has 'h'.
   • 5 vein has 'i'.
   • 4 venom has 'n'.
   • 2 verify has 'r'.

   Arranging these third letters alphabetically gives us the sequence: g, h, i, n, r.

4. Now, we match this alphabetical order of the third letters back to the original words and their corresponding numbers:

   • 'g' in vegan (3) comes first.
   • 'h' in vehicle (1) comes second.
   • 'i' in vein (5) comes third.
   • 'n' in venom (4) comes fourth.
   • 'r' in verify (2) comes fifth.

Determining the Correct Sequence

Based on the step-by-step comparison of the letters, the correct order of the word numbers as they would appear in an English dictionary is determined by the alphabetical order of their third letters (g, h, i, n, r).

Therefore, the correct sequence is:

3, 1, 5, 4, 2
