Question

What is the predecessor of natural number 1?
A.0
B.2
C.10
D.Does not exist

Answer 1

Hint:For this above question we have to find the predecessor = N-1, as N is referred to the natural numbers and by placing the above value we can get the value.
Where N is natural number, N-1 = 1-1 =0 ,
Complete step-by-step answer:
Predecessor refers to the previous term of a particular term while the successor refers to the next term of a particular term. In order to find the successor of a whole number, one must add one to the particular given number.In order to find a predecessor, one must subtract one from the particular given number.
In the above question we have to find predecessor of number 1 so we have to subtract 1 from that i.e N-1 ,where N is natural number we get,
N-1=1-1=0
As we know that 0 is not considered as a natural number ,
Thus, option D. does not exist is the correct answer.

Note: As a predecessor is considered as to the previous term of a particular term while the successor refers to the next term of a particular term. In order to find the successor of a whole number, one must add one to the particular given number. In order to find a predecessor one must subtract one from the particular given number.
