Proof by induction monotonic sequence

WebNov 16, 2024 · We call the sequence decreasing if an > an+1 a n > a n + 1 for every n n. If {an} { a n } is an increasing sequence or {an} { a n } is a decreasing sequence we call it monotonic. If there exists a number m m such that m ≤ an m ≤ a n for every n n we say the sequence is bounded below. The number m m is sometimes called a lower bound for the ... WebExpert Answer. Is proof by induction valid for arbitrarily large finite cases or infinite cases, or both? Recall the definitions: monotonic sequence, convergent, bounded, and Cauchy sequence. Knowing that bounded monotonic sequences converge, and that convergent sequences are Cauchy sequences, is it safe to conclude that Cauchy sequences are ...
