Understanding Dictionary Order for Word Arrangement

Arranging words in dictionary order, also known as alphabetical order, involves comparing them letter by letter from left to right. The word that comes first alphabetically is placed first, and so on.

Let's analyze the given words and their corresponding numbers:

1. Account
2. According
3. Accuracy
4. Accumulate
5. Accompany

All the words begin with the letters "Acc". We need to look at the letters that follow these initial three letters to determine the correct dictionary sequence.

Step-by-Step Comparison for Dictionary Sequence

We compare the words letter by letter starting from the fourth letter:

• Account: Account
• According: According
• Accuracy: Accuracy
• Accumulate: Accumulate
• Accompany: Accompany

Looking at the fourth letter:

• 'o' appears in Account, According, and Accompany.
• 'u' appears in Accuracy and Accumulate.

Words starting with 'o' come before words starting with 'u'. So, Accompany, Account, and According will come before Accumulate and Accuracy.

Comparing Words Starting with 'Acco'

Let's compare Accompany, Account, and According by their fifth letter:

• Accompany: Accom
• Account: Accou
• According: Accor

Comparing 'm', 'u', and 'r' alphabetically, 'm' comes first, followed by 'r', and then 'u'.

So, the order for these three words is:

1. Accompany (5)
2. According (2)
3. Account (1)

Comparing Words Starting with 'Accu'

Now, let's compare Accumulate and Accuracy by their fifth letter:

• Accumulate: Accum
• Accuracy: Accur

Comparing 'm' and 'r' alphabetically, 'm' comes first, followed by 'r'.

So, the order for these two words is:

1. Accumulate (4)
2. Accuracy (3)

Combining the Sequences

The 'Acco' group comes before the 'Accu' group. Combining the ordered lists:

1. Accompany (5)
2. According (2)
3. Account (1)
4. Accumulate (4)
5. Accuracy (3)

The correct sequence of numbers is 5, 2, 1, 4, 3.

Final Dictionary Arrangement

Thus, the words arranged in dictionary order correspond to the sequence 5, 2, 1, 4, 3.
