Is there any mathematical way for finding centre of clusters in
clustering issue?

As per Phil Sherrod, see

http://www2.chass.ncsu.edu/garson/PA765/cluster.htm

and look up "Cluster centers".

"Cluster centers are the average value on all clustering variables of each
cluster's members"

That's an arbitrary definition of the "center" of a cluster.

The "centroid method" is one way to find the "center" of a
cluster. There are other criteria just as arbitrary. Why
would anyone want to know the center of a cluster anyway?
