Reuse Patterns Using Capture Groups Problem

Tell us what’s happening:
I’m having trouble figuring out what exactly code camp is wanting my regular expression to look like. I cam up with one that works with all the test cases, but I still fail the check to see if I have only 2 spaces between each number. I made a regular expression that works correctly (using repeat groups as well as a beginning carat and negative lookahead), but it’s obviously not what they’re looking for. Can anyone help me out?

Your code so far

let repeatNum = "42 42 42";
let reRegex = /^((\d+)\s)\1\2(?!.)/; // Change this line
let result = reRegex.test(repeatNum);

I figured it out, they were wanting to see \s in two places, so I used
