Answer:
![26](https://tex.z-dn.net/?f=26)
.
Step-by-step explanation:
The given series is;
![\sum_{n=1}^{4}(n+4)](https://tex.z-dn.net/?f=%5Csum_%7Bn%3D1%7D%5E%7B4%7D%28n%2B4%29)
.
This series is finite and has few number of terms.
We can rewrite the expanded form to get;
![\sum_{n=1}^{4}(n+4)=(1+4)+(2+4)+(3+4)+(4+4)](https://tex.z-dn.net/?f=%5Csum_%7Bn%3D1%7D%5E%7B4%7D%28n%2B4%29%3D%281%2B4%29%2B%282%2B4%29%2B%283%2B4%29%2B%284%2B4%29)
.
![\sum_{n=1}^{4}(n+4)=5+6+7+8](https://tex.z-dn.net/?f=%5Csum_%7Bn%3D1%7D%5E%7B4%7D%28n%2B4%29%3D5%2B6%2B7%2B8)
.
![\sum_{n=1}^{4}(n+4)=26](https://tex.z-dn.net/?f=%5Csum_%7Bn%3D1%7D%5E%7B4%7D%28n%2B4%29%3D26)
.
