1) The negation of '" $\forall,n\in N, n+7>6$ " is ................ A) $\exists n\in N, $such that $n+7 \leq6$ B) $\exists n\in N,$ such that $n+7 \geq6$ C) $\forall n\in N, n+7 \leq 6$ D) $\exists n\in N, $such that $n+7 < 6$ Answer: Option AExplanation:Key Idea The negation of the quantifier forevery is there exists. Given statements '$\forall,"n\in N$", such that n+7>6" $\therefore$ The negation of the given statement is $\exists n\in N, $such that $n+7 \leq 6$
