If we use the 3-base system then we count 1,2,10,11,12,20,21,22,100, 101,102,110,111,120,121,122,

That instead of 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16

10=3 in decadic system

100=9 in decadic system

1000=27 in decadic system

10 000=81 in decadic system

100 000=243 in decadic system

222=80 in decadic system

The thhird number after 222 is 1002 in thye 3 base system and 83 in decadic system.

9____3_____1

2____2_____2

3____0_____0

3____0_____1

3____0_____2______answer

222, 1000, 1001, 1002, 1010, 1011, 1012, 1020, ...

Another way: 222 base 3 = 18+6+2 base 10 = 26 base 10. The 3rd numeral after that should represented 29, and 1002 base 3 does indeed equal 29 base 10.

The next number after 222 would be 1000

The 2nd number after 222, the number after 1000, would be 1001

The 3rd number after 222 would be 1002.

1000.

It's like you're base ten and the number is 999.
