If you want to add N days to your days  You can use the plus operator as follows -    SELECT   SYSDATE   N   FROM DUAL

Some disadvantage of  INTERVAL  1  DAY  is that bind variables cannot be used for the number of days added  Instead  numtodsinterval can be used  like in this small example   select trunc sysdate    numtodsinterval  x   day   tag from dual   See also  NUMTODSINTERVAL in Oracle Database Online Documentation

In a more general way you can use  INTERVAL   Here some examples   1  add a day  select sysdate   INTERVAL  1  DAY from dual    2  add 20 days  select sysdate   INTERVAL  20  DAY from dual    2  add some minutes  select sysdate   INTERVAL  15  MINUTE from dual
