Claim: {(-1)"} does not converge to any real number a. Proof: Assume that the sequence converges; that is, assume that there is an a E R such that lim,--.(-1)" = a. Then, using E = 1, from the definition of convergence, we know that there exists an no such that |(-1)" - al < 1 for all n > no. Thus, for any odd integer nno, we have |(-1)" - al = 1-1-a[< 1, and for any even integer n>...

does not Use the definition of convergence to explain why the seque converge to zero. – Definition 2.2.3 (Convergence of a Sequence). A sequence (an) converges real number a if, for every positive number €, there exists an N EN such that whenever n > N it follows that an - al < €. Ju To indicate that (an) converges to a, we usually write either lim an = a or (an) → a. The notation lim +00an =a is...

Does the sequence {an} converge or diverge? Find the limit if the sequence is convergent. 15n an = n +4 Select the correct choice below and, if necessary, fill in the answer box to complete the choice. O A. The sequence converges to lim an no (Type an exact answer, using radicals as needed.) OB. The sequence diverges.
