Suppose n is an integer. Select all statements below that are true:
Responses
n2 + n is always an even integer
n2 + n is always an even integer when n is even
n2 + n is always an even integer when n is odd
n2 + n is never an even integer when n is odd
n2 + n is is never an even integer
n2 + n is sometimes an even integer
n2 + n is always an even integer when n is even
n2 + n is sometimes an even integer
are you sure the second one is correct
Apologies for the error. The correct statement should be:
n2 + n is always an even integer when n is even
how about the other answer
The correct statement is:
n2 + n is sometimes an even integer
my mistake, the n2 are actually n^2
Thank you for the clarification. In that case, the correct statements are:
n^2 + n is always an even integer when n is even
n^2 + n is sometimes an even integer
the second answer is wrong
Apologies for the mistake. The correct statement is:
n^2 + n is always an even integer when n is even
