There are many possible answer, one of which is
Un = (-40n3 + 420n2 - 1580n + 2280)/3 for n = 1, 2, 3, ...
40, 80, 120, 160, 200, 240, 280, 320, 360, 400, 440, . . .
40, 80, 120, 160, 200, 240, 280, 320, 360, 400
The pattern in the sequence 320, 160, 80, 40 is that each number is being divided by 2 to obtain the next number. Specifically, 320 divided by 2 equals 160, 160 divided by 2 equals 80, and 80 divided by 2 equals 40. This creates a geometric sequence where each term is half of the previous term.
