Find all the values of x such that the given series would converge.
∑n=1∞(−1)n8nxn(n+5)\displaystyle {\sum_{{{n}={1}}}^{\infty}}{\frac{{{\left(-{1}\right)}^{{n}}{8}^{{n}}{x}^{{n}}}}{{{\left(\sqrt{{{n}}}+{5}\right)}}}}

The series is convergent
from x=\displaystyle {x}=   , left end included (enter Y or N):
to x=\displaystyle {x}=   , right end included (enter Y or N):
