To determine how many numbers are used more than three times in the given sequence, we should first count the occurrences of each digit from 0 to 9.

In the provided number sequence (012782167432186491237289167298), we analyze the frequency of each digit:

- 0 appears 1 time

- 1 appears 4 times

- 2 appears 5 times

- 3 appears 3 times

- 4 appears 2 times

- 5 appears 0 times

- 6 appears 3 times

- 7 appears 4 times

- 8 appears 3 times

- 9 appears 2 times

Next, we identify which digits appear more than three times. From the counts:

- The digit ‘1’ occurs 4 times.

- The digit ‘2’ occurs 5 times.

- The digit ‘7’ occurs 4 times.

These are the only digits that meet the criterion of appearing more than three times.

Thus, there are three digits (1, 2, and 7) that appear more than three times in the sequence. This reasoning leads us to conclude that the correct answer is indeed three, reflecting the proper analysis and counting of
