a(n) is the sum of the first a(n) digits

[Eric Angelini]

Hello SeqFans,

I like this seq :

S=1,10,11,12,20,111,112,120,1000,1001,1002,1003,1004,1005,1006,1007,1008,1009,1010,1011,1012,1013,1014,1015,1016,10000,10000000000,10000000800,10000000801,10000000802,10000000803,...

... where a(n) is the sum of the first a(n) digits. (Example: "12" says that the first 12 digits sum up to 12, which is true: 1+1+0+1+1+1+2+2+0+1+1+1=12)

Seq is monotonically increasing and every new term must be as small as possible.

Could someone check this (and compute a few more terms)?

Best,

É.
