Question

Enter the next 3 terms from the geometric sequence below.

Answer 1

Answer:

1/4, -1/8, and 1/16

Step-by-step explanation:

Geometric sequence:   -2, 1, -1/2, ....

Geometric sequence means there is a common ratio.

so from -2 , the next term is  -2*r , and the next term is -2*r*r

-2r = 1, means  r = -1/2

then next after -1/2,  is  1/4,

and then...   -1/8, and then  1/16
