Let a₁ , a₂ , a₃ , a₄ ,... .be a given sequence.
The common ratio of this sequence is the following:
a₂/a₁ = a₃/a₂ = a₄/a₃ = r
Example: 5, 25, 125, 625, ...The common ration is:
25/5 = 125/25 = 625/125 = 5. So r=5 is the common ratio
THE ANSWER IS D

Answer:
x = 3, v = -8
Step-by-step explanation:
Substitute x.

[5 •
= -73 - 11v]
Isolate v.
5
= -73 - 11v
v = -8
Substitute v.
x = 
x = 3
X=-11 :) let me know if you need more help!
