Answer 2

Answer:

n square - 1 is / by 8 if n is an odd number

Step-by-step explanation:

cause while squaring odd numbers we of course get an odd number and while subtracting one from it it would be divided by 8

for ex ; 3 square is 9 while 1 subtracted we get 8 which is divisible by 8 and it continues in this way
