Year CPI Year CPI Year CPI Year CPI
1988 3 1993 144.5 1998 163.0 2003 184.0
1989 0 1994 148.2 1999 166.6

1991 2 1996 156.9 2001 176.9
1992 3 1997 160.5 2002 179.9
Compute the inflation rate for each year 1989-2003 and determine which years were years of inflation. In which years did deflation occur? In which years did disinflation occur? Was there hyperinflation in any year?
