1937 and 7617. The first four terms seem to suggest a power sequence, such as U n = (-1/2)*(-4) n, but the last term does not fit. A possibility that fits all the five data of the points is: U n = (791n 4 - 8898n 3 + 34213n 2 - 52458n + 26400)/24 for n = 1 , 2, 3, ... This rule gives the answers above.
