# c_n = ((-1)^n)/(2 squareroot n)

## Question:

{eq}c_{n} = \frac {\left ( -1 \right )^{n}}{2 \sqrt n} {/eq}

## Convergence or Divergence:

When an alternating series converges and the corresponding absolute series ( the series made up of the absolute values of the terms ) diverges, we say the original series is conditionally convergent.

{eq}c_n=(-1)^n a_n {/eq}

The series {eq}\sum c_n {/eq}

converges if the {eq}\lim_{n \to \infty} a_n = 0 {/eq}

terms decrease to zero as the...
