Answer:
Ana is correct
Step-by-step explanation:
Given
Required
Determine who is right?
To do this, we simply test each sequence.
For Carlos:
When n = 1
When n = 2
<em>This is incorrect because the first and second term of the sequence are -10 and -4 not -4 and 2</em>
<em></em>
For Ana:
When n = 1
When n = 2
When n=3
When n = 4
This is correct.
<em>Hence, Ana is correct</em>

Answer:
x = 36°
Step-by-step explanation:
The sum of the exterior angles of a pentagon is always 360°. Since the pentagon is regular, meaning that all of its sides and interior angles are congruent, we know that all of the exterior angles are also congruent. Since a pentagon has 5 sides, we know that there are 5 congruent exterior angles, therefore:
5 * 2x = 360
10x = 360
x = 36°
