(180 * 2) * 3 + 200 * 2
360 * 3 + 400
1080 + 400 = 1480 feet
notice the first term is -10, and the common difference is 3, so we add 3 to get the next term.

check the picture below.
Answer:
midpoint formula:
x1+x2/2 y1+y2/2
-4 + (-2)/2 which then simplifies to -6/2 and then to -3
2 + 2 /2 which then simplifies to 2
x= -3
y= 2
so (-3,2) is the coordinate point of the midpoint of this segment
You haven't shared a fraction. Please do that next time.
I checked and have found that 0.045 repeating over the 4 and 5 is equivalent to 1/22. Try dividing 1 by 22 to verify this.
So I infer that the fraction you haven't yet shared is 1/22.
