Question 6 Is the above statement True or False? if (an)n is an increasing bounded below...
An increasing (or decreasing) sequence that is bounded is convergent. Select one: True False
Is the below statement True or False? If lim an=0 then a, must be convergent. n=0
6. True or False. If the statement is true, explain why using theorems/tests from class, and if the statement is false provide a counter example. (a) If an and are series with positive terms such that is divergent and an <by for all r, then an is divergent. I (b) If a, and be are series with positive terms such that is convergent and an <br for all 17, then an is convergent. (e) If lim 0+1 = 1 then...

- Let (xn) be a
bounded sequence ((xn) is not necessarily convergent), and assume
that yn → 0. Show that lim n→∞ (xnyn) = 0.
Question1.
All the
solution state that there exists M >0 and xn<=M . My question
is that why M always be bigger than 0 and Why it is bounded above ?
why it is not m<=xn bounded below????
Question.
2.
if the
sequence is convergent, then...
7. Determine whether the statement is true or false. If it is false, give an example that shows it is false. If it is true, prove it or refer to a theorem. (1) If {an} is divergent, then {an} is unbounded. (2) If {an} is bounded, then {an} is convergent. (3) If {an} converges and {bn} converges, then {an + bn} converges. (4) If {an) is convergent and {bn} is divergent, then {an + bn} is convergent. (5) If {an}...

5) Define the supremum of a bounded above set SCR. 6) Define the infimum of a bounded below set SCR. 7) Give the completeness property of R 8) Give the Archimedean property of R. 9) Define a density set of R. 10) Define the convergence of a sequence of R and its limit. 11) State the Squeeze theorem for the convergent sequence. 12) Give the definition of increasing sequence, decreasing sequence, monotone se- quence. 13) Give the...
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.

True or False: If n=1 an is a series with terms an which are nonnegative real numbers, and the partial sums N=1 an are uniformly bounded in- dependent of N E N, then n=1 An is a convergent series. If true, prove it; if false, give a counterexample.
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.
