Find the next two terms of this geometric sequence: 5, -10, 20, . . .


Sagot :

all you have to do is multiply it by two. And i think it's an alternate positive, negative pattern.
So:
5,-10,20,-40,80
Since it is a geometric sequence you multiply to get the next term

-10 divided by 5 is -2 as well as -20 divided by 10

so the next two terms are -40 and 80
