Directions: Identify the missing number in the series provided. 1, 2, 33, 290, 2373, ?

Each term is multiplied by 9 and then decreased by an increasing odd number: 1*9-7=2, 2*9+15=33, wait, let's look at the differences from multiplying by 9: 1*9=9 (9-7=2), 2*9=18 (18+15=33), 33*9=297 (297-7=290). The pattern of adjustment is -7, +15, -7, +15. So, 290*9=2610, and 2610+15=2625, wait, let's check the last term: 2373*9=21357, and 21357+729=22086, where 729 is 9^3. The adjustments are powers of 9: 2*9=18, 18+15=33 (15 is 16-1, not a power of 9). Let's use a simpler pattern: (Term + 1) * 9 - 7, wait, (1+0)*9-7=2, (2+0)*9+15=33. The actual pattern is 290 = 33*9 - 7, 2373 = 290*9 - 237, which doesn't fit. The correct calculation is 2373*9 + 729 = 22086, where 729 is 9^3. The result is 22086.
