sum from n=1 to infinity of 0.7^n

Lösung

n = 1 \sum \infty 0. 7^{n}

Lösung

2.33333 \dots

Schritte zur Lösung

n = 1 \sum \infty 0. 7^{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 0. 7^{n} - 0. 7^{0}

n = 0 \sum \infty 0. 7^{n} = 3.33333 \dots

= 3.33333 \dots - 0. 7^{0}

Vereinfache

= 2.33333 \dots
