The infinite series whose terms are the natural numbers 1 2 3 4 ⋯ is a divergent series The nth partial sum of the series is the triangular number ∑ k = 1 n k = n 2, {\displaystyle \sum _{k=1}^{n}k={\frac {n}{2}},} which increases without bound as n goes to infinity Because the sequence of partial sums fails to converge to a finite limit, the series does not have a sumThis proves (2), in view of the definition (26) of "for n ≫ 1" ¤ The argument can be written on one line (it's ungrammatical, but easier to write, print, and read this way) Solution Given ǫ > 0, ¯ ¯ ¯ ¯ n−1 n1 − 1 ¯ ¯ ¯ ¯ = 2 n1 < ǫ, if n > 2 ǫ −1 ¤ Remarks on limit proofs 1 The heart of a limit limits{n to ∞}1/nn/(n1)^2n/(n2)^2n/(2n1)^2 is equal to Sarthaks eConnect Largest Online Education Community \(\lim\limits_{n \to \infty}\left\frac 1n\frac n{(n1)^2}\frac n{(n2)^2}\frac n{(2n1)^2}\right to (1) 1/2 (2) 1 (3) 1/3 (4) 1/4 Login Remember Register Test

Course Title MATH 2294; We will need to use Theorem 2 on this problem To this we'll first need to compute, lim n → ∞ ( − 1) n n = lim n → ∞ 1 n = 0 Therefore, since the limit of the sequence terms with absolute value bars on them goes to zero we know by Theorem 2 that, lim n → ∞ ( − 1) n n = 0Section 3 Sequences and Limits Definition A sequence of real numbers is an infinite ordered list a 1,a 2,a 3, a 4, where, for each n ∈ N, a n is a real number We call a n the nth term of the sequence Usually (but not always) the sequences that arise in practice have a recog
Plugging in the next n into our partial sum formula we see that (n1)^2 = n^2n1, which is what we got earlier This shows that given a partial sum = n^2, all partial sums after that follows that pattern Then we simply do 13 = 2^2 to prove that there is a partial sum = n^2Et 2=2 2 Note that the requirement of a MGF is not needed for the theorem to hold In fact, all that is needed is that Var(Xi) = ¾2 < 1 A standard proof of this more general theorem uses the characteristic function (which is deflned for any distribution) `(t) = Z 1 ¡1 eitxf(x)dx = M(it)Thus the value of the infinite sum is a / (1r), and this also proves that the infinite sum exists, as long as r < 1 In your example, the finite sums were 1 = 2 1/1 3/2 = 2 1/2 7/4 = 2 1/4 15/8 = 2 1/8 and so on;
