Strange typecasting happening in loop - Powershell "System.Object[]" to type "System.Int32"."

Question

Trying to do a simple loop to populate an array

[array]$td= @()
[int]$test = 4
[int]$x = 0
for($x=1,$x -le $test, $x++)
{
$Temp = (Get-date).AddDays(-$x)
$td += Get-Date $Temp -Format dd/MM/yyyy
}
$td

Error message is due to type casting.. yet I am setting what I want them to be and also seem to be getting a spurious 0?

Error is

Line |

7 | for($x=1,$x -le $test, $x++)
| ~~~~~~~~~~~~~~~~~~~~~~~
| Could not compare "1" to "4 0". Error: "Cannot convert the "System.Object[]" value of type "System.Object[]" to type "System.Int32"."

You need to use semi-colons, not commas.

 [array]$td= @()
 [int]$test = 4
 [int]$x = 0
 for($x=1;$x -le $test; $x++)
 {
    "X={0}" -f $x 
    $Temp = (Get-date).AddDays(-$x)
    $td += Get-Date $Temp -Format dd/MM/yyyy
 }
 $td
