Is X odd?
1.) 2x-1 is odd
2.) x^3 is odd.
As per me the answer should be (B).
The answer is however C. The explanation is that to determine that X is an integer, we need statement 1.
But why do we need statement 1) to prove X is an integer? Since statement 2) says that x^3 is an odd no...which makes it evident that x is integer because only integers are classified as even or odd.
Am I going wrong here?? Please help!!
