Which of the following is not a property of Pascal’s triangle?


Pascal's Triangle has several important properties. Here are some common ones:

1. **Symmetry**: The triangle is symmetrical along the central axis.
2. **Binomial Coefficients**: Each element in Pascal’s Triangle represents a binomial coefficient, specifically \(\binom{n}{k}\) where \(n\) is the row number and \(k\) is the position in that row.
3. **Sum of Row Elements**: The sum of the elements in the \(n\)-th row of Pascal’s Triangle is \(2^n\).
4. **Fibonacci Sequence**: The sums of diagonals in Pascal’s Triangle correspond to the Fibonacci sequence.
5. **Triangular Numbers**: Certain diagonals of Pascal's triangle correspond to triangular numbers and other figurate numbers.

Without specific choices listed, it’s likely that one property not associated with Pascal's triangle could be something unrelated to binomial expansions or these sequences (e.g., non-triangular or non-Fibonacci sequences).

If you provide the specific choices, I can tell you which is not a property. Would you like to see an explanation of each of these properties?

### Follow-up Questions:
1. What is the relationship between Pascal's Triangle and binomial expansions?
2. Can you explain how the Fibonacci sequence is found in Pascal’s Triangle?
3. What are triangular numbers, and how do they appear in Pascal’s Triangle?
4. How is Pascal’s Triangle used in probability theory?
5. How do the powers of 2 relate to Pascal’s Triangle?

**Tip**: Each row in Pascal’s Triangle represents the coefficients of the expanded form of \((x + y)^n\).
