Question

Find the common ratio of the following geometric sequence.

If necessary, use the slash bar ( / ) to enter a fraction. Reduce fractions to their lowest terms.

(5/12),(1/3),(4/15),(16/75),(64/375)

Answer 1

I am pretty sure that the the common ratio of the following geometric sequence can be defined using this way: ( - 1 / 6 ) * ( 12 / 5 )
= - 2 / 5
As you know, to find the common ratio we use this - r = T3/T2
Hope it's clear! Do hope you will find useful!
