Finding Dictionary Order for Words

To arrange words in dictionary order, we compare them letter by letter from left to right. The word with the letter that comes earlier in the alphabet at the first point of difference comes first.

Let's list the given words with their corresponding numbers:

1. Paleobiology
2. Pacifistically
3. Paleoecology
4. Pantomimically
5. Palletization

Now, let's compare them letter by letter:

• All words start with 'P'.
• Comparing the second letter:
  • Pacifistically starts with 'Pac'.
  • Paleobiology, Paleoecology, Palletization start with 'Pal'.
  • Pantomimically starts with 'Pan'.

Since 'c' comes before 'l', and 'l' comes before 'n', "Pacifistically" (2) will come first. "Pantomimically" (4) will come last among these five based on the second letter.

Now let's order the words starting with 'Pal': Paleobiology (1), Paleoecology (3), Palletization (5).

• Compare the first four letters: All are 'Pale'.
• Compare the fifth letter:
  • Paleobiology (1)
  • Paleoecology (3)
  • Palletization (5)

Comparing 'b', 'e', and 't', the order is 'b', 'e', 't'.

So, the order for the 'Pale...' words is:

1. Paleobiology (1)
2. Paleoecology (3)
3. Palletization (5)

Combining the full list in dictionary order:

1. Pacifistically (2)
2. Paleobiology (1)
3. Paleoecology (3)
4. Palletization (5)
5. Pantomimically (4)

The numerical sequence corresponding to this dictionary order is 21354.

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