8,-4,2,-1 what are the 3 next numbers in there order?

Answer 1

These are the stupidest questions that we see. There are infinitely many answers.

One function can be f(x) = -4.5x^3 +36x^2 - 88.5x + 65.

So the 5th term will be f(5)=-40

Note f(1) = 8,

f(2)=-4

f(3)=2

f(4)=-1

And f(5)= -40

So the sequence is 8,-4, 2, -1, -40

Answer 2

The common ratio is -1/2

8, -4, 2, -1, 1/2, -1/4, 1/8, -1/16
