Answer:
Using the formula: S_{n} =\frac{n}{2} [2a_{1} +(n-1)d]S
n
=
2
n
[2a
1
+(n−1)d]
\begin{gathered}S_{27} =\frac{17}{2} [2(8) +(27-1)2]\\\\S_{27} =\frac{17}{2} [16 +(26)2]\\\\S_{27} =\frac{17}{2} [16 +(26)2]\\\\S_{27} =\frac{17}{2} [16 +52]\\\\S_{27} =\frac{17}{2} (68)\\\\S_{27} =\boxed{578}\end{gathered}
