Question

If n is an even number, which statement is true about n + 1?
A)
It is a prime number.
Eliminate
B)
It is an even number.
C)
It is an odd number.
D)
It is a perfect square.

Answer 1

C, guessing. N=even, adding one should make it odd.

Answer 2

If \(n\) is even, it is expressible as \(2k\) for some \(k\in\mathbb{N}\). Adding one yields \(2k+1\), which is not divisible by \(2\) and is therefore *odd*.
