    Sir, here’s a question regarding this chapter.

    The following data represents a time series :

    x 36 y 41 34 38 42

    A series of three point moving averages produced from this data has given the first two values as 38 39

    What are the values of (X,Y) in the original time series?

    *the given answer is (38,40) how do work this out?
