Answer:
X = 18
Step-by-step explanation:
X - 7 = 11
Add 7 to both sides
X - 7 + 7 = 11+7
X = 18
X=7/64 you multiply them by x first then do the math
8 is the answer because when you add 11+4 you get 16 and then you would subtract that from 24 which would give you 8. Idk where you got "PA" ?
The answer is...B. ways of maintaining relationships
a.
In order to find the common ratio, we just need to divide a term by the term that comes before it.
So using the terms 20 and -5, we have:

b.
The recursive rule can be found with the formula:

Where an is the nth term and q is the ratio. So we have:

c.
The explicit rule can be written as:

Where an is the nth term, a1 is the first term and q is the ratio. So:
