The difference between consecutive terms is $$111$$ times the $$n$$th Fibonacci number $$9 + 111 = 120$$ $$120 + 222 = 342$$ $$342 + 333 = 675$$ $$675 + 555 = 1230$$ $$1230 + 888 = 2118$$ $$2118 + (13\times111) = 3561$$ $$3561 + (21 \times 111) = 5892$$ And the next term would be $$5892 + (34 \times 111) = 9666$$
