An increasing (or decreasing) sequence that is bounded is convergent. Select one: True False
Question 6 Is the above statement True or False? if (an)n is an increasing bounded below sequence, then it must be convergent. True False
4. Determine whether the sequence is increasing, decreasing, or not monotonic. Is the sequence bounded? 3n - 7 a) b) an 7n+ 5 2 пл an = COS
6. Items 3 and 5 show that the sequence is bounded and increasing; hence, it is convergent call the limit e. Compute the 100th, 1,000th, and 100,000th term of the sequence to approximate e. Compare your results with the number e that your calculator will display. 6. Items 3 and 5 show that the sequence is bounded and increasing; hence, it is convergent call the limit e.

For each statement: True or false? Explain? If the terms sn of a convergent sequence are all positive then lim sn is positive. If the sequence sn of positive terms is unbounded, then the sequence has a term greater than a million. If the sequence sn of positive terms is unbounded, then the sequence has an infinite number of terms greater than a million. If a sequence sn is convergent, then the terms sn tend to zero as n increases....
True or False. If true, explain why. If False, gve a counterexample. If Σοη6" is convergent, Cnb is convergent, then Σ on(-2)" is convergent. True or False. If true, explain why. If False, give a counterexample. If Σ0n6n is convergent, then Σ cn(-6)n is convergent. True or False. If true, explain why. If False, gve a counterexample. If Σοη6" is convergent, Cnb is convergent, then Σ on(-2)" is convergent. True or False. If true, explain why. If False, give a...

6. Give an example of a non-constant sequence that satisfies the given conditions or explain why such a sequence does not exist: (1) {an} is bounded above but not convergent. (2) {an} is neither decreasing nor increasing but still converges. (3) {an} is bounded but divergent. (4) {an} is unbounded but convergent. (5) {an} is increasing and converges to 2.
Exercise 2.3.9. (a) Let (an) be a bounded (not necessarily convergent) sequence, and assume lim bn = 0. Show that lim(anon) = 0. Why are we not allowed to use the Algebraic Limit Theorem to prove this?
1. Determine an infinite sequence that satisfies the following ... (a) An infinite sequence that is bounded below, decreasing, and convergent (b) An infinite sequence that is bounded above and divergent (c) An infinite sequence that is monotonic and converges to 1 as n → (d) An infinite sequence that is neither increasing nor decreasing and converges to 0 as n + 2. Given the recurrence relation an = 0n-1 +n for n > 2 where a = 1, find...
