Answer : B.) f(x) =
The recursive formula f(x+1) = 4f(x)
Given : second term is 12 , so f(2) = 12
f(3) = 4f(2) = 4 * 12 = 48
f(4) = 4f(3) = 4*48 = 192
f(2) = 12 = 4* 3= 4*f(1). So f(1) = 3
f(1) =3 , f(2) = 12, f(3) = 48, f(4)=192.....
The sequence is Geometric
We use geometric sequence formula
, where 'a' is the first term and 'r' is the common ratio
a= 3 and r= 4
Explicit formula is
