1). n is not divisible by 2
So n is an odd number
n=1 - 0
n=3 - 0
n=5 - 0
So We will always get 0 as a remainder SUF
How is this sufficient ??
If n is a positive integer and r is the remainder when (n-1)(n+1) is divided by 24,
what is the value of r?
So we are asked to find the remainder. And in the first statement we all have 0 as the remainder when the number is divided by 24.
For example n=5
(n-1)(n+1) = 4x6=24 divided by 24 , remainder is 0
Now looking at my previous post, I realized that the only ODD number that will leave a different remainder is n=3
2x4=8 and when is divided by 24 , the remainder is 8
So it seems like A can not be sufficient because of the n=3 case.
Let's say what other will have to say :roll:
