    Another homework question from yet another person who hasn't read the rules about homework.

    Read this first: Expectations for the Homework Help board
    Do not simply retype or paste a question from your book or study material

    We won't do your homework questions for you.
    You were given the assignment for you to learn.

    If you come up with your own answer and post it for us to critique that is within reason.

    If you have some SPECIFIC questions that you couldn't find or didn't understand, we may help with that.
    But this is your assignment, so show us you have at least attempted to complete it on your own.

    First you need to know what will come after 12.

    Once you know that, the shortest way is to define this set of numbers as a equation.

    Then, there's a special formula that you can use to find the sum of all those numbers.
