If the mean of a set of observations is , then the mean of the observations is :
None
To find the mean of the observations , where , pattern of the new observations.
, we need to understand the pattern of the new observations.
Let's analyze the indices of the new observations:
When , the index of the new observation is which is not defined in this case.
When , the index of the new observation is ' which is also not defined.
For , the index becomes , which is not defined.
We can observe that for all ,the indices of the new observations are negative or beyond the given set of observations.
Since these observations are not defined, we cannot calculate their mean.
