Once you feel comfortable with these you should be able to do the unbracketed problems. These problems are due Monday January 11. \bigskip Do Problems [2.5], [2.9], [2.10], 2.17 and [2.28] from the text. \bigskip Do Problem 2.22 from the text. In addition, prove (by induction?) that the sequence$\{a_n\}$is either increasing or decreasing (you decide which). Next prove that the only possible limits of the sequence This is the end of the preview. Sign up to access the rest of the document. Unformatted text preview:$\{a_n\}$are of the form$\frac{1 \pm \sqrt{29}}{2}$. Use the fact below, to prove that the limit$\lim_{n \to \infty} a_n$exists and compute its value. \textbf{Fact.} A bounded monotonic sequence converges. \bigskip Do Problems [3.1], [3.2], [3.11], 3.25, 3.26, 3.32, 3.33+, 3.36, 3.41+. \bigskip \textbf{Problem A.} If two numbers between$1$and$100$are picked at random, what is the probability that the numbers differ by$15$? \bigskip \textbf{Problem B.} If a fair coin is tossed$3n\$ times determine the probability the number of heads is twice the number of tails? \end{document}...
