Answer 4

is 54 an odd number ?

Answer 5

no

Answer 6

hello

Answer 7

because 3+something produced an even number!

Answer 8

so can we say option B conflicts with the given conjecture ?

Answer 9

so what is the answer

Answer 10

option B

Answer 11

hello

Answer 12

The conjecture states that any number added to 3 is an odd number.
If you find a number added to 3 which is not an odd number, then that is a counterexample to the conjecture.
Look in the choices, and find a choice which is a number added to 3 whose result is not an odd. That is the answer.

Answer 13

A counterexample is an example that shows something different.
