    Consecutive Integers

    Hey, there's a problem I stuck on.

    Please explain how to actually do this, without making it a big deal like some teachers do.

    Problem:

    The 6 consecutive integers below add up to 447.

    x - 2
    x - 1
    x
    x + 1
    x + 2
    x + 3

    What is the value of x?

    6x+3 = 447 , solve for x

    Re: Consecutive Integers

    Ok, thanks. If you may confirm, 6x because there are 6 consecutive integers, which add up, (or as I'd like to say, equal) to 447, and the 3 stands for what exactly?

    If you add all six terms in that column, what term do you get.

    Re: Consecutive Integers

    -2 + -1 = -3

    -3 + 1 = -2

    -2 + 2 = 0
    0 + 3 = 3

    I have no idea what that is all about.
    You need direct tutorial help.
    Please see you instructor.

    Okay, you are adding -2+ (-1)+ 0+ 1+ 2+ 3, pairwise. Now, do you see where that "3" came from?

    x - 2
    x - 1
    x
    x + 1
    x + 2
    x + 3
    _____
    6x+ 3

    You asked him to add the numbers on the right and he did- getting the correct sum, 3.

    I used the word terms not numbers.
