HW6: Problem 4 (1 point) For each sequence an find a number k such that n* an has a finite non-zero limit. This is of use, because by the limit comparison test the series Can and n * both converge or both diverge.) n=1 n=1 A. an = (2 + 6n) -6 K = B. an = 6 notn K = C. an = - 3n2 +6n+3 4n4+6n+6 K = D. an = 3n2 + 6n+2 An' +6n +6vn, k =
