<h3>The common ratio of the sequence is -3</h3>
<em><u>Solution:</u></em>
<em><u>Given sequence is:</u></em>
-2, 6, -18, 54
We have to find the common ratio of sequence
Common ratio is the ratio between two consecutive numbers in the sequence
<em><u>Find the ratio of a term to its previous term</u></em>
![r = \frac{6}{-2} = -3\\\\r = \frac{-18}{6} = -3\\\\r = \frac{54}{-18} = -3](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B6%7D%7B-2%7D%20%3D%20-3%5C%5C%5C%5Cr%20%3D%20%5Cfrac%7B-18%7D%7B6%7D%20%3D%20-3%5C%5C%5C%5Cr%20%3D%20%5Cfrac%7B54%7D%7B-18%7D%20%3D%20-3)
Thus the common ratio of the sequence is -3
(4,-1). 4x+3y=13. You do 4(4)+3(-1)=13. hope that helps.
Answer:
A:∑j=15(2j−5)
Step-by-step explanation:
a = -3
d = -1 - (-3) = -1 + 3 = 2
j-th term: a + (j-1)d
-3 + (j - 1)(2)
-3 + 2j - 2
2j - 5
