infinite - you see there's: 5,14,23,41... then when it goes into thing like 123 and 132 etc... it goes on and on
WRONG IT IS NOT INFINITE!
123 does not add up to 5, nor does 132.
The answer is as follows.
5, 14, 23, 32, 41, 113, 122, 131, 212, 221, 311, 1112, 2111, 11111.

Answer: I cannot answer this question. I do not know where the numbers start and end. Answer: Put negative numbers before positive numbers. For the positive numbers, the one with the least digits is smaller. For the same number of digits, compare each digit until you find a different number of digits. For the negative numbers, it is the opposite as for positive numbers.
