64, –48, 36, –27, ...


Which formula can be used to describe the sequence?


f(x + 1) = 3/4 f(x)

f(x + 1) = -3/4 f(x)

f(x) = 3/4 f(x + 1)

f(x) = -3/4 f(x + 1)

The only formula that can be used to describe the sequence is definitely the third one \(f(x + 1) = -3/4 f(x)\). So count like that\(64* -\frac{3}{4} = -48 48* -\frac{3}{4} = 36\) and so on. You can check others by yourself to check if I'm right or not.
