Just need help with first two questions. <Prove the following statement.a-b is a factor of an - b[ Hint: ak+1-bk +1 = a(ak - bk) + bk (a−b)].CHEEEROA. No, because it can be shown that a-b is not always a factor of a +1 - bk+1 even when a - b is a factor of a - bB. No, because it cannot be assumed that a - b is a factor of a - b*.OC. Yes, because since it is assumed that a - b is a factor of a - bk, it is known that a-b is also a factor for n=k+1.k+1 k+1OD. Yes, because it can be shown that a-b must be a factor of aWhat is the conclusion? Choose the correct conclusion below.A. The statement is not true for n=1. It holds for k + 1, given that it holds for k. Therefore, by the Principle of Mathematical Induction, it only holds for the natural numbers, kk+1.- b if a - b is a factor of a - bkCOB.

Prove the following statement. a-b is a factor of a - b [ Hint: ak+1-bk +1 = a(ak-bk) + bk (a−b)]. FEED OA. No, because it can be shown that a-b is not always a factor of ak+1-bk+1 even when a - b is a factor of a - bk. OB. No, because it cannot be assumed that a-b is a factor of a - b OC. Yes, because since it is assumed that a-b is a factor of ak-bk, it is known that a-b is also a factor for n=k+1 OD. Yes, because it can be shown that a-b must be a factor of a +1 - b if a-b is a factor of a - bk What is the conclusion? Choose the correct conclusion below. A. The statement is not true for n=1. It holds for k + 1, given that it holds for k. Therefore, by the Principle of Mathematical Induction, it only holds for the natural number k+1. OB. The statement is true for n=1. It also holds for k +1, given that it holds for k. Therefore, by the Principle of Mathematical Induction, it holds for the first k + 1 natural m
