for($i=0; $i<=5;$i++)
{
$oe_sequence[$i]= $odd_sequence[$i]+$even_sequence[$i];// This statement //adds two arrays                                                                                                              //and assigns in oe_sequence array
}
for($i=0;$i<=5;$i++)
{
echo "$oe_sequence[$i]\n";                //Prints $oe_sequence value
                                                                    //here oe means odd even
