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.

Answer:
E = (-14, 15)
Step-by-step explanation:
The midpoint relation is ...
M = (D +E)/2
2M = D +E . . . . multiply by 2
E = 2M -D . . . . subtract D
E = 2(-4, 8) -(6, 1) = (-8-6, 16 -1)
E = (-14, 15)
Answer:
6
Step-by-step explanation:
Prime factorize 30: 2*3*5
Prime factorize 18: 2*3^2
The similarities are 2^1 and 3^1, and 2*3 is 6.
