Answer:
-1066.65 to 2 decimal places.
Step-by-step explanation:
(−800)+(−200)+(−50)+(−12.5)+...
This is a Geometric series with common ratio r =(-200) / ) / (-800) = 0.25 and first term a1 = -800.
Sum of n terms = a1 * (1 - r^n) / (1 - r)
Sum of 8 terms = -800 * (1 - 0.25^8) / (1 - 0.25)
= -800 * 1.333313
= -1066.65.
The coordinates are 68276528
