Question
Determine whether the statement is true or false. If true, provide a proof; if false, provide a counterexample. Let {xn} be a sequence of real numbers. (a) If {xn} is unbounded, then {xn} has no limit. (b) If {xn} is not monotone, then {xn} has no limit. (c) If {xm} converges, then there exists N E N such that rN+1 – xN| < 1/2N. (d) If |æn+1 - xn < 1/2" for all n E N, then {xn} converges. (е) If 21 = 1 and xn+1 = Xn + 1/n for n > 1, then {xn} is bounded.
