What is the common ratio for the geometric sequence 768,480,300,187.5

the common ratio is 0.625 or if you prefer 5/8

Step-by-step explanation:

Every geometric sequence has a common ratio which is a constant and is the quotient of any term divided by the term preceding it.  In this case:

r=480/768=300/480=187.5/300=0.625

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70

7000

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
