Since you always assemble your steps in increasing order, you could do this: 

#!/usr/bin/perl
use strict;
use warnings;

my ($first, $second, $steps) = @ARGV;
$steps = int $steps;

if ($first > $second) {
   ($first,$second) = ($second,$first);
}
my $increment = ($first - $second) / ($steps - 1);
my @array     = ($first);
for (2..$steps) {
    push @array, $first -= $increment;
}

print join(", ", @array) . "\n";
