Is P-1 always even?
P is prime.
P=2k+1, where K is any positive integer.
Guys,this is a yes/no question and I got a bit confused by the word "always" in the question.Please correct me:
Stmt 1: If P=2,P-1 =odd
If P is any other prime P-1 will be odd.
Hence, NO P-1 IS NOT ALWAYS EVEN
Checking for A/D
Stmt 2:Similar process.NO P-1 IS NOT ALWAYS EVEN
But if the word "always" was'nt there we can safely say that the OA is correct..
