avoids three-term monotone arithmetic progressions. Consequently, this arrangement
avoids k-term monotone arithmetic progressions in [n] for k≥ 3. Hence, we are interested in
finding an arrangement of [n] that avoids k-term monotone arithmetic progression, but allows
k− 1-term monotone arithmetic progression. In this paper, we propose a method to rearrange
the rows of a magic square of order 2 k− 3 and show that this arrangement does not contain …
