–81, 108, –144, 192,
which formula can be used to describe the sequence?
a. f(x) = –81(4/3)^x-1
b. f(x) = –81(-3/4)^x-1
c. f(x) = –81(-4/3)^x-1
d. f(x) = –81(3/4)^x-1

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 !
