WebSolution Verified by Toppr Correct option is A) Given ∑ r=0n (r+1)C r2 It can be written as ∑ r=0n r⋅C r2+∑ r=0n C r2 We know that r⋅ nC r=n⋅ n−1C r−1 Hence r⋅C r2=n⋅ n−1C r−12 … Web13. Prove that the Cauchy product of two absolutely convergent series con-verges absolutely. Note: Given P a n and P b n, we put c n = P n k=0 a kb n−k and call P c n the Cauchy product of the two given series.

Webwe find thataB 1 ≡1 (mod 167). Similarly, aB i ≡1 (mod 167) for all i. Since 167 is a prime and 167 −1 = 2 ·83, we know that the order of each individual a i (since a i ̸= 1) must be either 2 of a multiple of 83. If Bis not a multiple of 83, then it follows that all the a Web(n+1)! r!(n−r +1)! = n+1 r Lemma 1.2 n r is an integer, for n,r integers with n ≥ 0, 0 ≤ r ≤ n.
