Revise PowerShell Script

I have a script (that came from a previous question). This script creates new computers off of an existing computer template.

As I am still working with PowerShell, I would like to see how it can be approved in efficiency or syntax. The script is currently working but I am sure it can be better.

If it can be improved, can you also explain why an improvement should be made?

Add-PSSnapin Quest.ActiveRoles.ADManagement


$SourceComputer=Read-Host "What will be the computer template?"
$Computer=Get-QADComputer $SourceComputer
$ParentContainer=$Computer.ParentContainer
$Groups=Get-QADComputer $SourceComputer | Get-QADMemberof


$prefix = Read-Host "What is the computer prefix? EX: GAMCN or GAMCLABN"
try { [int]$startnumber = Read-Host "What number would you like to start with? EX: 01 or 13" -ea "Stop"}
catch {"Need to enter a number"; break}
try { [int]$number = Read-Host "How many computer accounts do you want to create?" -ea "Stop"}
catch {"Need to enter a number"; break}
ForEach ($i in ($startnumber..($startnumber + $number -1)))
{
  $compName = $prefix + $i
  New-QADComputer -name $compName -ParentContainer $ParentContainer
  
  foreach ($Group in $Groups) {
  Add-QADGroupMember $Group $compName}

}
