Answer:
the mistake is in the first statement.
Explanation:
Now lets us put the statement into consideration:
"The sum of any two rational numbers is irrational"

The negation is not "the sum of any two rational numbers is irrational"
Therefore the mistake is in the first statement and it is due to incorrect negation of the proof.
