which set is infinite?
P = {positive numbers less than 60}
Q = {whole numbers between 10 and 20}
R = {intergers ge=reater than 18}
S = {even numbers between 5 and 15}

R because the others all have set limitations. R is the only one that makes sense! Since numbers can go on forever that means numbers greater than 18 would be infinite!
