Schritte zur Lösung

n = 1 \sum \infty (\frac{1}{3})^{n}

n = k \sum \infty (a_{n}) = n = 0 \sum \infty (a_{n}) - a_{0} - a_{1} - \dots a_{k - 1}

= n = 0 \sum \infty (\frac{1}{3})^{n} - (\frac{1}{3})^{0}

n = 0 \sum \infty (\frac{1}{3})^{n} = \frac{3}{2}

= \frac{3}{2} - (\frac{1}{3})^{0}

Vereinfache

\frac{3}{2} - (\frac{1}{3})^{0} : \frac{1}{2}

= \frac{1}{2}
