The two consecutive numbers whose factors have the same sum are 8 and 9. The factors of 8 are 1, 2, 4, and 8, and their sum is 15. The factors of 9 are 1, 3, and 9, and their sum is also 15. Therefore, 8 and 9 are the consecutive numbers whose factors have the same sum.

There are none. There are two odd numbers next to every even one, so finding 3 consecutive numbers of the same kind is impossible.
In numerical order, with no missing numbers. 1, 2, 3, and 4 are consecutive. 1, 3, 4, and 2 are the same numbers, but are not consecutive because they are not in order. 1, 3, and 4 are not consecutive because 2 is missing.
1 and 0 are the two whole numbers with their sum same as their difference
Write them in a column. Since there is only one number per row, there is no chance of consecutive numbers being in the same row.
