setTimeout and array each

I'm confused with using setTimeout and the each iterator. How can I rewrite the following so that the console outputs each name after a delay of 5 seconds? Currently the code below prints all the names at once after 5 seconds. I would like to:

1) wait 5 seconds, then print kevin

2) wait 5 seconds, then print mike

3) wait 5 seconds, then print sally

var ary = ['kevin', 'mike', 'sally'];



_(ary).each(function(person){



  setTimeout(function(){

    console.log(person);

  }, 5000);    



});

You could create a variable called offset that makes the timer wait 5 seconds more for each person in the array, like so:

var ary = ['kevin', 'mike', 'sally'];



var offset = 0;

_(ary).each(function(person){



  setTimeout(function(){

    console.log(person);

  }, 5000 + offset);    

 offset += 5000;

});
