For sake of convenience, reverse the series, then it would be:
21,19,17.....7
a=21, d = -2,
s(4) = 4/2 (21+15)
s(4)=2(36)
s(4) = 72

Step-by-step explanation:
Midpoint =(\frac{x_{2}+x_{1}}{2},\frac{y_{2}+y_{1}}{2})
Answer:
Midpoints of line CD are (-2,2).
Step-by-step explanation:
The midpoints is given by

As given
The endpoints of CD are C(−4, 7) and D(0,−3).
Putting values in the above


Midpoints = (-2,2)
Therefore midpoints of line CD are (-2,2).
