It is an ordered set of numbers such that the difference between adjacent numbers is a constant.
{1, 2}, {7, 8} and {10, 11}. The triangular numbers are 1, 3, 6, 10, 15, 21, 28, ... The sum of two adjacent numbers is odd, so adjacent numbers that sum to 1, 3, 15, 21 are the solution. 1 is impossible, leaving 3, 15 & 21 as possible sums, giving the adjacent numbers {1, 2}, {7, 8} & {10, 11}
Contour numbers.
