Answer:
We have been given many sequences below:
The sequence is said to be geometric if there is same ratio between consecutive terms

So we will check all the sequences one by one:
(1) 

.
Hence, geometric
(2) 


Hence, geometric.
(3) 


Hence, geometric.
(4) 


Hence, geometric.
(5) 

Ratio is not same hence, not geometric.
The answer is 4 1/2 and that's the answer
10 1/5 = 10.2
10.2 - 15.5= -5.3
Let
LE-----------> represent the linear expression
we have that
<span>[-4y + 2 ]+LE=y
LE=y-[-4y+2]-------------> LE=y+4y-2-----------> LE=5y-2
the answer is
</span>the linear expression is (5y-2)<span>
