Question

How can we find out the successor of a number?

• A. by adding $1$ to the number
• B. by finding out the next number with a number line
• C. by adding $10$ to the number
• D. (a) and (b) above.

Answer 1

The correct option is D (a) and (b) above.

Let's try and understand this with the help of an example.

Suppose we have to find the successor of the number $45$.

When we do $45+1=46$, it gives us the successor.

On drawing a number line, we see that $46$ is the number immediate next of $45$, which makes it a successor of $45$.




So we can find the successor of a number in both these ways.

But $45+10=55$, which is not a successor of $45$ so that option is incorrect.
