Infinity is undefined
✌

Answer 2

HeY THErE!!

Actually,
            Infinity has no value, it's neither -1/12 nor any other value
   that does exhibit any value.
 Actually today scientists know only 0.0001 % of the universe, when we will reach 100% , then we will able to answer value of infinity. Infinity does not have a value. 
It's not a number or a value is a limit that no one can find it out
hope it helps
