You are talking about analyzing data in a regular time series.  R has
wide ranging time series analysis packages.  I would suggest starting
with the basic package that comes with an R download and reading the
basic information associated with it.  You could also checkout Venables
and Ripley, _Modern Applied Statistics with S [which R is a dialect
of].  If this is a homework question, hit the books.
