I am just learning about regular expressions and I need help finding one to validate a number in a text box that is in the following format

1111 111 11111

Allowed are all numbers and two spaces
not allowed every other character

Can someone help

Are the spaces always in the same place, or can they appear anywhere in the string?

You're welcome!
Assuming any sequence of digits, no leading nor trailing nor consecutive spaces allowed, then the following should do:
^(?:\d+ ){2}\d+$
