The differences between consecutive terms are: 8793-8450=343=7³, 9009-8793=216=6³, 9135-9009=126, 9198-9135=63. The pattern of differences should be 7³, 6³, 5³=125, 4³=64. The difference 126 breaks the pattern (should be 125), making 9135 the wrong number. If 9009+125=9134, then 9134+64=9198, which fits.
