Use summation notation to express the given infinite series.

- 1 + 2 - 4 + 8 - 16 + \dots

\sum_{n = 1}^{\infty} (- 1)^{n} \cdot 2^{n - 1}

\sum_{n = 1}^{\infty} (- 1)^{n - 1} \cdot 2^{n - 1}

\sum_{n = 1}^{\infty} (- 1)^{n + 1} \cdot 2^{n - 1}

\sum_{n = 1}^{\infty} (- 1)^{n} \cdot 2^{n + 1}

\sum_{n = 1}^{\infty} (- 1)^{n} \cdot 2^{n}
