    it looks like you increase by an amount to get to the next term... but the amount you increase changes with each term. Can you see the pattern?

    almost the right idea, but I think you are going the wrong direction... what are the next three terms after 0? Should be getting larger, I think...

    -30 ---> -14 increases by 16 -14 ---> -6 increases by 8 and so on...

    Almost.. but you broke the pattern :) to get from -6 to -2, increase by 4 to get from -2 to 0, increase by 2 (half as much as last increase) So... to get from 0 to the next term, increase by ___ to get ____

    well... those sound like the amounts of the increases, right? not the actual terms in the sequence? The term you just found was "1". So the next increase from 1 gives you the second term.

    hehe... so so close... Remember, it's increasing every time. So the last term given was 0, and you increased correctly by 1 to get 1. Then you increased again correctly by 0.5 to get 1.5 Finally, you increase FROM 1.5 by 0.25 to get ?? :)

    Good for you... just have to concentrate and not lose focus as you work through the pattern. Was this homework for you too, or just something you were watching because it was interesting?
