Which natural numbers have no predecessor a) 0 b) 1 c) 10 d) 100
Answer: b) 1
Natural number 1 is the only one that does not have a predecessor.
Explanation
Predecessors are numbers that come before the given number. The whole number 0 comes before the natural number 1.
Predecessor and Successor
The most common mathematical terms for describing a series or sequence of whole numbers are Predecessor and Successor. Before and after numbers are used to refer to a predecessor and a successor.
Successor
In mathematics, the term “successor” refers to the term immediately following the term or value immediately preceding it. If n is a whole number, then n+1 is the next logical step. The next value is another term for a successor.
Predecessor
A predecessor is a value that precedes another value. If a value is x, then its predecessor is x – 1. As a result, we must subtract the given value from 1 to find its predecessor.
