Let's take n as 3 and 3^2 is 9.
9-1 is 8 and 8×3 is 24.
Hence we can say that it is divisible by 24.You can take any value that is odd for n and you will get the number that is divisible by 24.

GeniusYH: can you do without trial and error method
Vishall94: I dont know if we can do it without hit and trail but since the value is not that big, it can be done with hit and trail mentally.
