WebIt is also bounded below because 1 n ≥0 1 n ≥ 0 for all positive integers n. Therefore, { 1 n} { 1 n } is a bounded sequence. On the other hand, consider the sequence {2n} { 2 n }. Because 2n ≥2 2 n ≥ 2 for all n≥ 1 n ≥ 1, the sequence is bounded below. However, the sequence is not bounded above. Therefore, {2n} { 2 n } is an unbounded sequence. WebJun 5, 2024 · Although the Natural numbers are bounded below (by 0) they are not bounded above so it is possible for an infinite set of natural numbers to have no maximum. (Although it could; A finite set will have a maximum element). 2) This is true for integers. Every set of integers that is bounded below will have a least element.
Webbounded below if there exists L such that, for all n, a n ≥L; L is a lower bound for ( a n); bounded if it is both bounded above and bounded below. Example 1.

After a little thought you might go on to say that the sequences WebArea between a curve and the x-axis. The shaded region is bounded by the graph of the function f (x)=2+2\cos x f (x) = 2+ 2cosx and the coordinate axes.
WebWe can also see that the sequence is bounded above by 1, as follows: ai = (i – 1) / i = i/i – 1/i = 1 – 1/i <= 1 [since -1/i is negative] Since {a i } is increasing and bounded above, it converges to the least upper bound of the sequence. In this case, the least upper bound is 1, so {a i } converges to 1.
