TIMTOWTDI (easy to follow, but not very Perl-ish); assumes a constant offset, but adapt as required: 
my @origin = (2, 3, 22, 17);
my @offset = (4,5);

my $n = 0;
my $p = 0;

for my $origin(@origin) {
    push(my @interesting_cell, $origin[$n] + $offset[$p]);
   $n++;
   $p++;
   if ( $p > 1 ) { $p = 0 };
   for my $interesting(@interesting_cell) {
      print "$interesting \n";
   }
}

prints:

Afterthought: OP clearly doesn't want the output formatted this way, but can use the values as desired.
