Question

What is the common ratio of the following geometric sequence 5/12, 1/4,3/20,9/100,27/500

Answer 1

3/5

Explanation

Ratio =second term divided inti first term a2/a1

a1=5/12 a2=1/4

1/4: 5/12 is the same as 1/4*12/5 =12/20 = 3/5

5/12*3/5 = 15/60 = 1/4

1/4* 3/5 =3/20

3/20*3/5 =9/100

9/100 *3/5 = 27/500..........
