We have to represent the fraction 
in two different ways.
Let us multiply the numerator and denominator of the given fraction by '2'.
Therefore, 
Therefore, 
is the first way to represent the given fraction.
Now, Let us multiply the numerator and denominator of the given fraction by '3'.
Therefore, 
Therefore, 
is the second way to represent the given fraction.
Therefore, and are the different ways to represent the fraction .
Answer:
First term: -10
Fourth term: -55
Eighth term: -115
Step-by-step explanation:
I am assuming the means -5(3n-1). To find the first term, plug in 1. You will get -5(3*1-1) or -5*2 or -10.
To find the fourth term, plug in 4. You will get -5(3*4-1) or -5*11 or -55.
To find the eighth term, plug in 8. You will get -5(3*8-1) or -5*23 or -115.
So the answers are -10, -55, and -115.
162 is the next in the sequence. It's a sequential value. Just multiply the previous number by 3, and you have you answer.
