Answer:

Step-by-step explanation:
General arithmetic sequence formula: 
where
= first term, and d = common difference.
The first term is -8
And the common difference appears to be - 7 as 7 is subtracted to get to the next term. Ex. -8 - 7 = -15, -15 - 7 = - 22 and so on.
To get the explicit formula of the sequence we simply plug in the values of a1 and d the general arithmetic sequence formula
General formula: 
We have
and d = -7
So the formula to find the nth term would be

Answer:
D
Step-by-step explanation:
To find the average, add up all of the values and then divide by the number of values.
So first, add (-5) + (-4) + (-7) + (-2) + (2) + (5)
You get -11. Then, divide -11 by the number of values (6)
-11/6 is about -1.83, which rounds to -2
Answer:
Straight Angle
Explanation:
Def: An obtuse angle is an angle whose measure is greater than 90 degrees but less than 180 degrees. Def: A straight angle is an angle whose measure is exactly 180 degrees. Def: Two angles are congruent if their measures are exactly the same. Def: Two angles are complementary if their measures add up to 90 degrees.
