Answer:
[tex]26[/tex].
Step-by-step explanation:
The given series is;
[tex]\sum_{n=1}^{4}(n+4)[/tex].
This series is finite and has few number of terms.
We can rewrite the expanded form to get;
[tex]\sum_{n=1}^{4}(n+4)=(1+4)+(2+4)+(3+4)+(4+4)[/tex].
[tex]\sum_{n=1}^{4}(n+4)=5+6+7+8[/tex].
[tex]\sum_{n=1}^{4}(n+4)=26[/tex].
