Question

Which rule is a recursive rule for the sequence 1,-6,36, -216

Answer 1

Answer: 1*6°=6

1*(-6)^1=-6

1*(-6)^2=36

1*(-6)^3=-216

Answer 2

3rd option

Explanation:

There is a common ratio between consecutive terms , that is

r = - 6 ÷ 1 = 36 ÷ - 6 = - 216 ÷ 36 = - 6

To obtain a term in the sequence multiply the previous term by - 6

Then the recursive rule is

`a_(n)` = - 6 .
`a_(n-1)`
