SQL & PL/SQL

Hi Guru,
Great day is today.
I want to print out the count based filter in where clause

select count(*) from mytable where SYS_CREATED_ON > SYSDATE-&N;

here, N -> number of days before. Let say 3; 

What I want 
SYS_CREATED_ON           CNT
10_JAN_2023              210524
09_JAN_2023              112568
08_JAN_2023              546783

Thanks
