Identify describe and extend each pattern 64,55,46,37,28,19

You subtract 9 each time. 10, 1, -8, -17, -26

You are subtracting 9 each time, or, if you are a visual learner, an easier way to understand it could be that the left digit always goes down 1 and the right digit goes up 1. So because of the found pattern, the next numbers would be 10...1...-8...-17...-26...-35...-44...-53... And so on. Something to remember is that when you start getting into the negative numbers, the visual pattern goes vice versa. The left number goes up 1, and the right number goes down 1, when there are negative numbers. Whereas for positive numbers, left goes down 1, and right goes up 1. If you don't get what i am saying, stare at it long enough and you'll then understand what I am meaning lol. Hope I helped
