Question

Write the recursive formula for the sequence

-3,-6,-12,-24,-48, ...

Answer 1

Explanation:

find the volume of a pyramid with a square base, where the perimeter of the base is 10.4 in and the height of the pyramid is 9.6in

Answer 2

`a_(n)` = 2
`a_(n-1)`

Explanation:

The recursive formula allows a term in the sequence to be found by multiplying the previous term by r the common ratio.

r = - 6 ÷ - 3 = 2 , then

`a_(n)` = 2
`a_(n-1)` ; a₁ = - 3
