Why is the set of all natural numbers is said to be not interval while, the set of all real numbers greater than 0 is considered as intervals?Define the reason clearly in simple words.

Answer»

Set of natural numbers is differ by 1, 

Hence it is not continuous and not dense while \(\mathbb{R}\)is dense.

So, and subset of \(\mathbb{R}\) is called an interval but subset of \(\mathbb{N}\) does not called an interval
