Is there any natural number that has no predecessor?
$$\textbf{Step 1: Checking for the smallest natural number.}$$
$$\text{The range of natural numbers is from 1 to infinity}$$
$$\therefore$$ $$ \text{The smallest natural number is 1.}$$
$$\textbf{Step 2: Checking for the predecessor of 1}$$
$$\text{The predecessor of 1 i.e. } 1 - 1 = 0$$
$$\text{But 0 is a whole number and not a natural number}$$
$$\therefore \text{1 is a Natural number that has no predecessor.}$$
$$\textbf{Yes, there is a natural number that has no predecessor, which is 1.}$$
