Question

Write the predecessor and successor of one

Answer 1

Predecessor: The predecessor of a natural number is one less than the given number.

So, the predecessor of $1$is $=1-1=0$

Successor: The successor of a natural number is the number obtained by adding 1 to it.

So, the successor of $1$ is= $1+1=2$

Hence, the successor and the predecessor of $1$ are $2and0$respectively.
