The replacement game (Posted on 2021-03-09) Difficulty: 3 of 5
The triplet (n-1, n, n+1) is written on a board where n is positive integer. A move consists of choosing two of the numbers a and b, replacing them with 2a-b and 2b-a thus creating a new triplet. After a succession of moves, two of the numbers are zeros. Find all possible values for n.
