Hint: For the above question first of all we will have to know about the term successor and predecessor. The term successor and predecessor in maths signify that are directly after or before a particular number, respectively. Furthermore, this applies only to whole numbers. Successor and predecessor are called after number and before number respectively. 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.
Complete step-by-step answer:
Let us suppose that we have a number “a” then the successor and predecessor of the number is \[(a+1)\text{ and }(a-1).\]
Now the difference between the successor and predecessor is as follows:
\[(a+1)-(a-1)=2\]
Hence, the difference between the successor and predecessor is equal to 2.
Therefore, the correct option of the above question is option C.
NOTE: Just remember the concept of successor and predecessor as it will help you a lot in this type of question.
