Hello again!

I have three arguments: initial value, step and number of members. I need to create a string as follows: 
# for example:
$initValue = 2;
$step = 3;
$numOfMembers = 5;

# wanted string is:
$str = '2 5 8 11 14';

Like arithmetic sequence. How can I create the string efficiently?
Of course I can do:
my $str = $initValue;
for (my $i=2; $i<=$numOfMembers; $i+=$step) {
   $str .=  ' ' . ($initValue + $step($i-1));
}

But I'm sure there's elegant ways than that.
If it matters or not, $step will always be 1 or 2 (according to another parameter I have lets say ($isDoubleStep)).

Thanks
