Find the average of the two indicated real numbers. \[ -\frac{1}{7} \text { and } \frac{2}{13} \]

Step 1 ：To find the average of two numbers, we add them together and then divide by 2. In this case, we need to add \(-\frac{1}{7}\) and \(\frac{2}{13}\), and then divide the result by 2.

Step 2 ：The average of the two numbers is \(\boxed{0.005494505494505503}\).
