What is the goal of a proof by contradiction? A. The truth of the statement cannot be determined, so the proof is
invalid.
B. The contradiction of the statement is proven false, so the original
statement is therefore proven true.
C. The contradiction of the statement cannot be determined, so the
proof is invalid.
D. The contradiction of the statement is proven true, so the original
statement is therefore proven false.

Asequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. if f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence? (1 point) f(1) = 2 and f(n) = f(n − 1) + 4; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2n; n > 1 f(1) = 2 and f(n) = f(n − 1) + 4n; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2; n > 1 i will award !
