For Alison's triangle, when n is an odd number the y axiswill always end in 10 but when it's even the y axis will always end in 0 for the top points of the triangle but for the bottom 2 pionts on each triangle will end in 5

(left corner of the triangle is 1, for the middle corner of the trianlge is 2 and the right corner of the triangle is 3) for the x axis, the formula will be, of number 1, n-1, for number 2, it will be n+1, and for number 3, it will be n+3.

your faithfully
David and Oliver. :)
