If x is an odd number, x^2 must be odd => (x^2+1) must be even. By the same logic, (x+5) is even. As addition of two odd numbers results in an even number. Multiplication of two even numbers results in an even number

Answer:
No, if x is an even number then 2x+1 is not even.
Step-by-step explanation:
This could be verified by substituting even values for x.
if x = 2,
then 2×2+1
4+1 = 5, which is odd.
if x= 4, then 2×4+1 =9 which is odd.
Hence , if x is even the 2x+1 is not even.
