sum from n=1 to infinity of 3(0.6)^{n-1}

n = 1 \sum \infty 3 (0.6)^{n - 1}

converges

Solution steps

n = 1 \sum \infty 3 \cdot 0. 6^{n - 1}

Apply the constant multiplication rule:

\sum c \cdot a_{n} = c \cdot \sum a_{n}

= 3 \cdot n = 1 \sum \infty 0. 6^{n - 1}

Apply Series Ratio Test:

converges

= 3 converges

= converges

n = 1 \sum \infty \frac{2 ^{n}}{7 ^{n}}

n = 1 \sum \infty \frac{2}{6 ^{n}}

n = 1 \sum \infty n^{3} + 1

k = 3 \sum \infty \frac{1}{( k - 2 ) ^{5}}

n = 3 \sum \infty \frac{1}{n !}
