# 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.
