(4m – 5) – (6m – 7 + 2n)

a. (4m – 5) + (6m + 7 + 2n)
b. (4m – 5) + (–6m + 7 + 2n)
c. (4m – 5) + (–6m – 7 – 2n)
d. (4m – 5) + (–6m + 7 – 2n)

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 !
