Well what you would do is see how it started at -14 right? Well you would have to add all the way up until you get to 12 so that would be starting at : -13,-12,-11,-10,-9,-8,-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7,8,9,10,11,and then you should get 26 of those numbers and its rising an easier way to do this would to just add 12+14 but yk. I hope this helped.
