Now, if we plug in a specific value for \(n\text{,}\) we do get a statement. In fact, it turns out that no matter what value we plug in for \(n\text{,}\) we get a true implication in this case. What we really want to say is that for all values of \(n\text{,}\) if \(n\) is prime, then \(n+7\) is not. We need to quantify the variable.
