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:
She will walk and run 148.2 miles in a year
