Explanation:

To understand this concept, let's consider a few examples.

Example 1:
Suppose we have the number 5. If we add 1 to 5, we get 6. And as per the statement, the sum should be the successor of the number we started with. In this case, 6 is the successor of 5.

Example 2:
Let's take another number, say 10. If we add 1 to 10, we get 11. Again, the sum (11) is the successor of the number we started with (10).

Proof:

Let's prove this statement mathematically.

Let's assume the number we start with is 'x'.

If we add 1 to 'x', the sum is (x + 1).

We need to prove that (x + 1) is the successor of 'x'.

To prove this, we need to verify if (x + 1) satisfies the properties of a successor.

1. Property 1: (x + 1) is greater than 'x'.
- This is true because adding 1 to any number always results in a greater number.

2. Property 2: (x + 1) is not equal to any other number between 'x' and its successor.
- This is also true because the only number between 'x' and (x + 1) is 'x' itself (as there are no other integers between two consecutive integers). And (x + 1) is not equal to 'x' because we added 1 to 'x'.

Hence, we can conclude that adding 1 to any number always gives us its successor.

Therefore, the correct answer is option 'B' (one).

It's when because if we add any
number with one so it's answer
will be its successor only.

Successor --

the number which comes after
adding 1 to any number or the
just after number of any
number is known as it
successor.
