The sequence 100, 88, 78, 70, 64, 60 is decreasing, with the differences between terms being 12, 10, 8, 6, and 4, indicating a decreasing pattern. The differences themselves decrease by 2 each time. The nth term can be expressed as ( a_n = 100 - (n-1)(12 - 2(n-2)) ), which simplifies to ( a_n = 100 - 6n^2 + 18n - 12 ).
