10,11,12,13,14,15,16,17,20,22,24,31,

100,121,144,169,196,225,256,289,400,484,576,961

My argument, 100 aand 121 are the squares of the first two numbers 10 and 11 so I continued giving the squares of all the remaining numbers in the sequence leaving squares of 100 and 121

any hints??

... 121, 10000, 1111111111111111

... 144, 238

and here's my reasoning:

10+10 = 20, 11+11 = 22, 12+12 = 24, and 14+17 = 31,

so then 10 x 10 = 100, 11 x 11 = 121, 12 x 12 = 144, and 14 x 17 = 238

doesnt quite fit the beginning of the sequence.... but cool observation..

There are only 2 more numbers in the sequence:

10000, 1111111111111111

Basically the sequence is just the number 16 in each of the different bases from 16 to 1:

16 in base 16: 10

16 in base 15: 11

16 in base 14: 12

etc...

16 in base 3: 121

16 in base 2: 10000

16 in base 1: 1111111111111111
