Question

Some one help me solve this problem. I have the answer.
What is the next term in the geometric sequence 16, –4, 1, – 1/4 , … ?
A. – 1/8
B. 0
C. 1/16
D. 1/8
E. 1/2

Answer 1

since this is a geometric sequence then it means it has to have a common ratio
the common ratio can be found by dividing a term by it's previous term

Answer 2

so the next entry can be found by multiplying the term before by the common ratio

Answer 3

saying the same thing but using different words
to get from the first term to the second term multiply by the common ratio, r
to get from the second term to the third term multiply by the common ratio, r
to get from one term to the next consecutive term multiply by the common ratio, r
