This sequence seems to follow a pattern where each number appears as many times as its value. Specifically:

• 1 appears once,
• 2 appears twice,
• 3 appears three times,
• 4 appears four times.

The next number should logically be 5 and should appear five times.

Thus, the continuation of this pattern would be:

5 5 5 5 5

Let me know if you'd like more details or explanations!

Relative questions:

1. What would be the 30th term in this sequence?
2. How would the sum of the first 20 terms of this sequence be calculated?
3. Can you describe a general formula to find the position of a number in the sequence?
4. How many times does 10 appear in this pattern if extended indefinitely?
5. What is the average value of the first 15 terms?

Tip: Recognizing patterns early can help simplify many mathematical problems, especially in number theory or sequences.
