Looking through the answer prompts, all of them require D to be true aside from 3)
So first check D. The prompt does not specify that \(N\) must be an integer.
\(\text{let }N = 0.5\\\\
2N+1 = 0.5 \times 2 + 1 = 2. \text{ (Even), so }\color{red}{ \text{false}}\)
3) B,C

A) The Average of N Consecutive integers is an integer for N being Even. False. For consecutive integers when number of integers is even, average= middle two terms/2= O+E/2 (can not be an integer)
B) The Average of N Consecutive integers is an integer for N being Odd. The middle term will be the average, and this term is odd integer.
C) The product N(N+1)(N+2) for integer N must be divisible by both 3 and 6. Either the product will be 0 or will have multiple of both 2 and 3 and 6. True.
D) 2N+1 is always Odd irrespective of N. What if =1/2, then 2N+1= 2
only B and C are true.
