now let's tackle this one so, here we're gonna which throughout this blue dot years on the right so if we started at 11 we started 11 you make two jumps to go to -5 so after add to -11 to get to -5 i have to add 6 so if i had six over two jumps that means that each of these jobs that must be plus three and this one must be plus three so now each each mark we just add three so -5 plus three so plus three is going against a negative to you plus three gets us to positive one -2 plus three is positive one plus three gets us to for so you're getting 826 here we get two for now list tackle this one so where -7 or this is nigga 7 this is one in the reef figure out this mark read over here so if you take two jobs to the right from negative 721 how much did we have to add well get from negative 721 you have to add 8 you have to at eight so that if we make another two jobs to the mystery number that means we at it again so one-plus 8 is 9 another way we could have thought about it if we added eight over two jobs at ways we added four on each job so this one must be negative 3 at four you get to one at four you get 25 ad for you get 29
