Answer:
3³
Step-by-step explanation:
Using the rule of exponents
= 
Given

= 
= 3³
(-6,26) are the coordinates of the other endpoint because it it the same distance from the midpoint in the opposite direction of the other endpoint
The answer is 327. Remember that when you multiply a number by ten, you move the decimal point to the right one place.
Hope that helped you.
You use explicit funtion to find a particular number in the list without needing to write all the list down.
For example, the first range of number has a constant difference of 5. Its explicit funtion would be: x(n)=3+(n-1)*5 (with x is the number you need to find, n is the number's position in the range)
Basically, a explicit funtion in that problem has the form:
x(n)=f+(n-1)*d
with:
x= the number needed to find
n= the number's position
f = the first number in the range
d = the distance
Good luck!
