This question examines your understanding of sequences and convergence. Please tick all correct statements. (Try to deduce the statements from facts you know, or try to find counterexamples, i.e. find examples showing that the statements are false.) You gain marks for every correct statement you tick, and you lose marks for every incorrect statement you tick. In total, the lowest number of marks you can score for this question is zero. (If you tick more incorrect than correct statements, your marks for this question will be set to zero.) a. A sequence (x) in Rn is said to converge to x in Rn if for every >0, there exists a number m in N such that ||XK-x|lse for all kzm. b. Let (xk) in Rn be a sequence, and let (yk) in Rº be the sequence defined by yk:=max(xj:jzk). Then (yk) is monotone increasing. c. A sequence (xk) in Rº is said to converge to x in Rn if there exist numbers >0 and m in N such that ||XK-X||≤ for all kzm. d. Let (xk) in Rn be a sequence, and let (yk) in Rº be the sequence defined by yk:=min{xj:jzk). Then (yk) is monotone decreasing.

A sequence (xk) in Rn is said to converge to x in Rn if for every >0, there exists a number m in N such that ||XK-X||≤& for all k≥m. b. Let (x) in Rn be a sequence, and let (yk) in Rn be the sequence defined by yk:=max{xj:j≥k}. Then (yk) is monotone increasing. C. A sequence (xk) in Rn is said to converge to x in Rn if there exist numbers >>0 and m in N such that ||x₁-x||≤ for all kzm. d. Let (xk) in Rn be a sequence, and let (yk) in Rº be the sequence defined by yk:=min{xj:j≥k}. Then (yk) is monotone decreasing.
