Piece of code to show the most recent post, for the second-most recent, etc.

Hi everyone,

I’m searching for three piece of codes.

One for the most recent post.

An other piece of for the second-most recent post.

And one piece of code for the third-most recent post.

So
<?php xxxxxx ?> for most recent

<?php xxxxxxx?> for the second-most recent.

Etc.

Can someone help me?
