Question

A successor of the number is located on the ____ side of a given number on number line.
A) Left
B) Right
C) Below
D) None

Answer 1

Hint: We will first write the definition of “successor” and get to know a bit about it. Then, we will evaluate the same on the number line, by drawing a number line for the same.

Complete step-by-step answer:
Let us first understand the meaning of successor.
Successor refers to the next term of that particular term.
For example: if we talk about a successor of 1, the number next to it which is 2 will be its successor.
This means that we need to add 1 to the particular number whose successor we need to find.
Let us now look at some numbers to clarify the same on the number line.
Take for instance a negative integer like -8, if we add 1 to it, we will have: -8 + 1 = -7 which obviously lies to the right of the number line than -8.
Now, consider 0 as the number whose successor we require. So, we get:- 0 + 1 = 1 which lies on the right of zero on the number line.
Look at the number line given below:

Red is the number whose successor we need to find and green would be the result if we add 1 to it.
Hence, green is in the right to the red.

Hence, the correct option is (B).

Note: The students must take care that there are two terms ‘Predecessor’ and ‘Successor’ and do not get confused in between these terms. Let us get to know about a way to remember these. “Success” somehow refers to “going ahead” or “moving forward”. So, we add 1 to go ahead the number and get a “successor”. The left term “Predecessor” is obviously the term which takes the number by 1 unit backwards. We need to subtract 1 from the given number to find its predecessor.
