Getting a Date value based on day

Hi,

I have a scenario like this.

I get a file on anyday of the week, so the file name is like this.
Code:
FILE_NAME_YYYYMMDD

I want to get the tuesday date before this day.

For example
FILE_NAME_20180413 I should get the date as 20180410
FILE_NAME_20180404 I should get the date as 20180403

Ho could I do that?

Thanks!!
