Suppose the cluster centre for variable A in cluster 1 is 80.1. Suppose cluster 1 contains 7 multivariate observations. A new multivariate observation, whose cluster centre for variable A is 42, is then added to cluster 1. To 2 decimal places, what is the new cluster centre for variable A in cluster 1?
