On Monday, Avi walked from his home to the school track and
ran 4 laps around the track for a total of 3.5 miles. On
Saturday, Avi walked from his home to the school track, ran 2
laps, and then walked home, for a total of 4 miles. Let x
represent the distance from Avi's home to the school track,
and let y represent the distance of one lap around the track.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

the anwser is d) 75°
