the next term in the geomatric sequence -1, -2,-4, is -6
true or false

- 8

Step-by-step explanation:

The real problem is that you should asked for the term after the next one.

Given what you have, the next term is likely 2*-4 = -8. That is one way to derive it.

Another would be to start at 0.

y = - 2^(n - 1)

n = 1

- 2^ ( 1-1) = -1 * 2^0

anything to the 0 power = 1 except 0. You cannot have 0^0 power.

Since 2 is not 0 then 2^0= 1

-1*1 = -1

n = 3

-2^(3 - 1) = -2^2 = - 4

Now you can keep on going from there.

I've shown you two ways to get - 8

I think that is your  intended answer

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9
