I need to find & replace a number (ej: 100004) for a consecutive ascending sequence figure (ej: 100004 / 100005 / 100006 and so on).

I found that i can find any sequence of numbers with 6 digits (or more, but i need fixing a 6 digit) in the "find" slot by typing "[0-9][0-9][0-9][0-9][0-9][0-9]" but i cant seem to fill the "REPLACE" slot correctly so that the program replaces the 6 digit number for an ascending consecutive sequence.

Can anyone help me with this?

(sorry for my poor english its not my first language)
