Describe the pattern and find the next two terms in the sequence. 8, - 4, 2, - 1, ...

U have a geometric sequence and ur multiplying each number by - 1/2 to get the next term.

8 * - 1/2 = - 8/2 = - 4

-4 * - 1/2 = - 4/-2 = 2

2 * - 1/2 = - 2/2 = - 1

-1 * - 1/2 = 1/2

1/2 * - 1/2 = - 1/4

so ur next 2 terms are : 1/2 and - 1/4
