Answer:
Option D. [tex]272[/tex]
Step-by-step explanation:
we know that
To evaluate the sum , use the formula
[tex]S=\frac{1}{2}(a1+an)n[/tex]
where
a1 is the first term
an is the last term
n is the number of terms
In this problem
For n=1 ------> a1=2(1)=2
For n=16 ------> an=2(16)=32
n=16 terms
substitute in the formula
[tex]S=\frac{1}{2}(2+32)16[/tex]
[tex]S=272[/tex]
