Answer:
The sum is equal to ![-905,200](https://tex.z-dn.net/?f=-905%2C200)
Step-by-step explanation:
we know that
The formula to calculate the sum is equal to
![Sn=n\frac{(a1+an)}{2}](https://tex.z-dn.net/?f=Sn%3Dn%5Cfrac%7B%28a1%2Ban%29%7D%7B2%7D)
In this problem
-----> number of terms
a1 is the first term
![a1=(-3(1)-4)=-7](https://tex.z-dn.net/?f=a1%3D%28-3%281%29-4%29%3D-7)
an is the last term
![an=(-3(775)-4)=-2,329](https://tex.z-dn.net/?f=an%3D%28-3%28775%29-4%29%3D-2%2C329)
substitute
![Sn=775\frac{(-7-2,329)}{2}=-905,200](https://tex.z-dn.net/?f=Sn%3D775%5Cfrac%7B%28-7-2%2C329%29%7D%7B2%7D%3D-905%2C200)
