Question

Find the common ratio of the sequence 512,256,128,...

Answer 1

Answer:

The common ratio is $\frac{1}{2}$

Step-by-step explanation:

Common ratio can be found out be dividing the 2nd term with the first, or the 3rd term with the 2nd, and so on.

2nd term= 256

1st term = 128

Common Ratio, r=$\frac{2nd Term}{1st Term}$

                          r=$\frac{128}{256}$

                          r=$\frac{1}{2}$
