Anyone know the answer?

Last one and the bottom answer choice is y=(x-4)^2+1 you guys!

What is the value of n in the equation -1/2(2n+4)+6=-9+4(2n+1)

Someone answer this asap for the first five terms of a sequence are shown. 5, 11, 23, 47, 95, . . which recursive function defines the nth term in the sequence for n > 1? a. f(n) = f(n - 1) + 6 b) f(n) = f(n - 1) + 48 c) f(n) = 3 • f(n - 1) + 1 d) f(n) = 3 • f(n - 1) - 4
