Is this an example of a mathematical predicate?
Post Body
A question I have is
For each set of conditions below, give an example of a predicate P(n) dened on N (natural numbers) that satisfy those conditions (and justify your example), or explain why such a predicate cannot exist.
I had this idea for the first question: "P(n) is True for n 5 and n = 8; False for all other natural numbers."
is
n (subset symbol) {1, 2, 3, 4, 5, 8}
a predicate in the first place, and if so, is this answer correct?
