sum from n=1 to infinity of 4/(sqrt(n))

n = 1 \sum \infty \frac{4}{n}

diverges

Solution steps

n = 1 \sum \infty \frac{4}{n}

Apply the constant multiplication rule:

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

= 4 \cdot n = 1 \sum \infty \frac{1}{n}

Apply p-Series Test:

diverges

= 4 diverges

= diverges

n = 1 \sum \infty \frac{1}{5 n - 1}

n = 2 \sum \infty (- 0.6)^{n}

n = 1 \sum \infty cos (\frac{14}{n})

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

n = 1 \sum \infty \frac{1}{n ^{2} + 10}
