You're almost there: 
#!/usr/bin/perl

use strict;
use warnings;

my $count;
do {$_ = <DATA>; print} until /formulae/ && ++ $count == 2;

__DATA__
One line
two line
formulae
blue line
red line
formulae
more line
more line
formulae
final line

That will print: 
One line
two line
formulae
blue line
red line
