At a party with 100 people, there is a pie. The first guest gets 1% of the pie, the second gets 2% of what's left, the third gets 3% of what's left after that, etc.
If the \(n^\text{th}\) guest gets the largest piece of all 100, what is \(n?\)

This is the graph of \(r=\frac{\sin4\theta}{\sin\theta}\) in polar coordinates.
Rotating the graph about the \(x\)-axis produces a volume of \(\frac{a}{b}\pi\), where \(a\) and \(b\) are coprime positive integers.
What is \(a+b?\)

Let \(F_n\) denote the \(n^\text{th} \) Fibonacci number, where \(F_1 = 1, F_2 = 1,\) and \(F_{n+2} = F_{n+1} + F_{n} \) for \(n=1,2,3,\ldots. \)
Define \(f_n (x) \) as a least-degree polynomial that passes through the coordinates \[(x,y)= (1, F_1), (2,F_2) , (3,F_3) , \ldots , (n-1, F_{n-1}).\] Hence, we define the expected Fibonacci sequence \(^e F_n \) to be equal to \(f_n (n). \)
For example, with \(F_1 = F_2 = 1\) and \(F_3 = 2,\) we have \(f_4 (x) = \frac12\big(x^2-3x+4\big), \) so \(^e F_4 = f_4 (4) = 4. \)
Find the closed form of the limit below (submit your answer to three decimal places): \[ \lim_{n\to\infty} \dfrac{ \big|^e F_n - F_n \big|}{F_n}.\]
Notation: \( | \cdot | \) denotes the absolute value function.
