Question: Find the interval of convergence:

1. \[\sum\limits_{n=1}^{\infty }{\frac{{{(-1)}^{n+1}}{{5}^{n-3}}}{{{4}^{n+2}}}}{{(x-1)}^{\begin{smallmatrix}
   n+1 \\
   \end{smallmatrix}}}\]
2. \[\sum\limits_{n=1}^{\infty }{\frac{3\cdot 5\cdot 7\cdot 9\cdot \cdot \cdot (2n+1)}{{{10}^{n}}(2n+1)(n-1)!}}{{(x+5)}^{n}}\]
3. \[\sum\limits_{n=1}^{\infty }{\frac{n{{4}^{n+1}}}{(n+2)!}}{{(x-4)}^{n}}\]
