The common ratio between any two consecutive terms in a geometric sequence is found by dividing the second term by the first term.
In this sequence, the second term is 3 and the first term is 1.5.
So, the common ratio is:
3/1.5 = 2
Therefore, the common ratio of this sequence is 2.
Given the geometric sequence:
1.5 3, 6, 12, ....
What is the common ratio?
