Analyze the sequence 1, 8, 19, 106, 510, 1771, 4858, 11299, 23311, 43930, 77141 using sequences of differences. (Enter your answers as a comma-separated list of values ordered with respect to increasing n.) first differences: second differences: third differences: fourth differences: fifth differences: From what degree polynomial does this sequence appear to be drawn? (Don't bother finding the coefficients of the polynomial.)
