# Stunning Summation

Algebra Level 5

$\sum _{ n=1 }^{ \infty }{ \frac { { 8 }^{ n } }{ \left( 3n-1 \right) ! } } =\frac { A }{ B } { e }^{ -C }\left( { e }^{ D }-E\sin { \left( \frac { \pi }{ F } +\sqrt { G } \right) } \right)$

If $$A,B,C,D,E,F$$ and $$G$$ are positive integers satisfying the equation above, find $$\min(A+B+C+D+E+F+G )$$.

Hint: Algebraic approach is easier than calculus approach.
