Answer:
5 and negative 5
Step-by-step explanation:
The absolute value is the distance from 0 five and negative 5 are both the same distance from zero
Mean= (5+6+5+6+9)/5= 7.2 coins
Explanation: The mean is the average of a data set. Add the numbers from the data set and divide by how many numbers.
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:
Answer:
3850m^2
