Row number of Filtered Row

[HWL]

Is there a simple way of getting the row number of the filtered row (supposing the user has filtered to a single row)?

Code so far:
=IF(SUBTOTAL(3,DB_LIST!B2:B300)=1,"yes 1 row","")

Where it says "yes 1 row", I'd like to return the row number that is actually filtered. I have done this will helper columns but I should be able to do it without a helper column. Thanks

This worked, found it in another answer:

=MATCH(TRUE,INDEX((SUBTOTAL(3,OFFSET(DB_LIST!$B$2:$B$300,ROW(DB_LIST!$B$2:$B$300)-ROW(DB_LIST!$B$2),0,1))*ROW(DB_LIST!$B$2:$B$300))>0,0),0)+ROW(DB_LIST!$B$1)
