sum from n=1 to infinity of 1/(2n(2n-1))

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

converges

Solution steps

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

Apply the constant multiplication rule:

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

= \frac{1}{2} \cdot n = 1 \sum \infty \frac{1}{n ( 2 n - 1 )}

Apply Series Integral Test:

converges

= \frac{1}{2} converges

= converges
