It’s is step 3 plz give me a branlist
Answer:
The general form of geometric series is ⇒ 
Where a is the first term and r is the common ratio
The sum of n terms of the geometric series is ⇒ 
For the given geometric series 2, 8, 32, 128
The first term is a = 2
The common ratio r = 8/2 = 32/8 = 128/32 = 4
So, 
And the sum of the given terms:
n = 4
∴ 
By using the given information about the inverse relation, we will get:
- Equation: y = -28/x
- Solution: y = -14

How to get the relation between x and y?</h3>
First, we know that y varies indirectly with x, then we can write the relation as:
y = k/x.
Where k is a constant.
Then, we know that when y = 7, we have x = -4.
Replacing these we can find the value of k:
7 = k/(-4)
7*(-4) = k = -28
Then the relation between x and y is:
y = -28/x.
Now, we want to find the value of y when x = 2, then we just replace that in the above equation:
y = -28/2 = -14
So we have:
- Equation: y = -28/x
- Solution: y = -14
