This sequence follows a pattern where each number appears multiple times before the next number in the sequence starts. Here is the breakdown:

• 3 appears once.
• 4 appears twice.
• 5 appears three times.

Based on this pattern, the next number will be 6, which should appear four times (since 6 follows the number 5, and the count of repetitions is increasing by one each time).

So, the next number is 6.

Tip: When identifying patterns in sequences, look for repetition or changes in intervals between numbers.
