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:
30
Step-by-step explanation:
= 170 + 15 - 5 (3+16) - 64 + 4
= 170 + 15 - 95 - 64 + 4
= 30
Answer:
Zachary is 9, Nicole is 8, and Jaycob is 27.
Step-by-step explanation:
x=Zachary
y=Nicole
z=Jaycob
x+y+z=44
x*3=z
x-1=y
However, for now, let's just assume that x and y are actually the same, and that the answer is actually 45.
so, x*3=z, and y*3 also equals z.
This is so that technically, 45/5=x, because z accounts for 3, and both x and y account for 1 each, meaning altogether it should be 5 you should be dividing by. 45/5=9, so x=9. Now that we have that figured out, we can solve the rest easily. 9-1=8, so there's your y, and 9*3=27. 27+9=36, and 36+8=44.
No. If no right angle exists, then it's not a rectangle.
