Question

The successor of -22 is
A. -23
B. -21
C. 23
D.21

Answer 1

Hint: On an integer number line, successor is the integer which is present right next to the given integer. So first draw the integer number line mentioning -22 and its neighboring integers and then find the next integer of -22 to get the answer.

Complete step-by-step answer:
To find a successor of a number, we can just add 1 to the number whereas to find a predecessor of the number we can just subtract 1 from the number. Successor is always greater and predecessor is always less than the given number. Successor is always present to the right side of the given number whereas the predecessor is always present to the left side of the given number on a number line.
We are given to find the successor of -22.
First let us draw the integer number line which indicates -22.

For positive integers, as the line progresses the values of the numbers increase whereas for negative integers as the line progresses the values of the numbers decrease.
So as we can see in the above integer number line diagram, the right next integer of -22 is -21. Therefore, the successor of -22 is $-21$.
So, the correct answer is “Option B”.

Note: Another approach to solve the given question.
If a number is of the form ‘n’ then we can determine the successor of n by adding 1 to it. Therefore, the successor of n is $ n + 1 $
Here we are given to find the successor of -22, this means n is -22.
