Will it work, 

data class;
set sashelp.class;
sequence=_n_;
run;

PROC REPORT DATA=WORK.CLASS LS=102 PS=56  SPLIT="/" CENTER ;
COLUMN  Name Sex Age Height Weight sequence;

DEFINE  Name / DISPLAY FORMAT= $8. WIDTH=8     SPACING=2   LEFT "Name" ;
DEFINE  Sex / DISPLAY FORMAT= $1. WIDTH=1     SPACING=2   LEFT "Sex" ;
DEFINE  Age / SUM FORMAT= BEST9. WIDTH=9     SPACING=2   RIGHT "Age" ;
DEFINE  Height / SUM FORMAT= BEST9. WIDTH=9     SPACING=2   RIGHT "Height" ;
DEFINE  Weight / SUM FORMAT= BEST9. WIDTH=9     SPACING=2   RIGHT "Weight" ;
DEFINE  sequence / SUM FORMAT= BEST9. WIDTH=9     SPACING=2   RIGHT "sequence" ;
RUN;

you created variable in data step block.
but i want to create variable in proc block(proc report)

[Kurt_Bremser]

Run a data step first, and use _n_ to create the sequence.

[Ksharp]

proc report data=sashelp.class nowd;
columns  name age weight n;
define name/display;
define n/computed 'Sequence';
compute n;
 _n+1;
 n=_n;
endcomp;
run;
