Consider a proof by contradiction of the following statement:
"If a and y are any two odd integers, then their suma+y is an even integer."
What is the beginning assumption in a proof by contradiction?
Note: The proof begins as follows:
Suppose to the contrary that...
z and y are even integers and their sum z + y is an odd integer.
If I and y are any two odd integers, then their sum x +y is an odd integer.
and y are even integers and their sum x + y is also an even integer.
If a and y are any two even integers, then their sum x + y is an odd integer.
z and y are odd integers and their suma+y is also an odd integer.
and y are odd integers and their sum + y is an even integer.
If z and y are any two even integers, then their sum x +y is an even integer.
