    If you start with drawing the points on a graph, then you will see what kind of variation it is, and the question will be much easier to solve.

    Plot your points, and the answer will come out like magic, believe me.

    Explain! Also, to avoid mis-communications, please post the value of the answer, not just the letter at the beginning.

    I don't know until I see your plot, and explain to me how you got it.

    A 7th grader should be able to make plots on graph paper. If he/she does enough of them, it will be obvious what the graph looks like by just looking at the numbers. Math is practice and patience. It's never too late to start!
