A is the correct answer also the angle in the diagram too.
Observe that as the series progresses, the term decreases by 1/4. To show this, observe the first four terms of the series below.
-200 = (1/4)(-800)
-50 = (1/4)(-200)
-12.5 = (1/4)(-50)
Since we have a common ratio, r, of 1/4, we can use the properties of a geometric series to find the 8th term of the series.
Recall that to find the sum of the nth term of a geometric series, we have

where a is the first term of the series and r is the ratio.
So, for the first eight terms, we have


Therefore, the sum of the 8th series is approximately -1066.65.
Answer: -1066.65
If one mile is 1760 yards, to find 1/8 of a mile in terms of yards, we can divide 1760 by 8.
1760 yards / 8 = 220 yards
