Why doesn't any odd multiple of 3 can give "24

x=1⇒y=0

x=3⇒y=1/3

x=5⇒y=1

x=7⇒y=2

x=9⇒y=10/3

x=11⇒y=5

x=13⇒y=7

x=15⇒y=28/3

x=17⇒y=12

x=19⇒y=15

x=21⇒y=55/3

.

.

^{-1}(x^{2}-1)=y" as a result (y) a natural number? Obviously no even number will make "y" a natural number, but all of the odd numbers do, but odd multiples of 3 (3, 9, 15, 21, 27...).x=1⇒y=0

x=3⇒y=1/3

x=5⇒y=1

x=7⇒y=2

x=9⇒y=10/3

x=11⇒y=5

x=13⇒y=7

x=15⇒y=28/3

x=17⇒y=12

x=19⇒y=15

x=21⇒y=55/3
