So I have got a file which contains lines like this : 

```
Peter Nagy 3 4 6 7 4

```

I need a Power shell script which asks the user to give a name, and it maths out the avarage of thoose numbers next to that name. Please help :) 

```
$name1 = read-host 
$content = Get-Content test.txt
$talalt = $content | Where-Object { $_ -match  $name1 }

```

I have no idea what to do after this, and how to get out of thoose numbers from that string.

Thanks in advance
