Find the common ratio and the three terms in the sequence after the last one given.
1) 3,-6,12,-24
2) -1,-5,-25,-125
3) 9,-3,1,-1/3
4) -5, -5/2, -5/4, -5/8

Step-by-step explanation:

If there is a common ratio it can be found by dividing any term by the one before it.

1. The common ratio is -6/3 = -2.

The following three terms can be found by multiplying the last given term by this number, then repeating that process two more times.

The next three terms are (-24)(-2) = 48; (48)(-2) = -96; (-96)(-2) = 192

___

2. The common ratio is -5/-1 = 5

3. The common ratio is -3/9 = -1/3

4. The common ratio is (-5/2)/(-5) = 1/2

Note that the signs of the terms of the sequence alternate when the common ratio is negative.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
