The given sequence;–3.2, 4.8, –7.2, 10.8, is a geometric progression common ratio of -1.5.
<h3>What is a geometric series?</h3>
When all the terms of a geometric sequence are added, then that expression is called geometric series.
The given sequence ;
–3.2, 4.8, –7.2, 10.8, …
The common ratio
= -4.8/ 3.2
= - 1.5
The terms having a common ratio of -1.5 best describe the relationship between the successive terms in the sequence of the terms.
