Predicate Logic with Inequality

598 Views Asked by At

I have the following sentence which I have to formalize using first-order logic.

"All #'s greater than or equal to one are greater than themselves divided by four"

Is it correct to say: ∀x(x≥1) → (x > x/4)

If so, would the negation be: ∃x¬(x≥1) ∧ ¬(x > x/4)

If this isn't correct, how would I be able to do it?

Thanks in advance!

the quantifier must cover the entire formula: $$ \forall x\left(x\geq1\rightarrow x>\frac{x}{4}\right) $$
