Question

Match the numbers to their successors.

• A. $130$
• B. $101$
• C. $1001$
• D. $100$

Answer 1

There are two ways to find a successor.
1) Add $1$ to the number
2) Observe the number scale.

For $129$, the successor is $129+1=130$

For $99$, the successor will be $99+1=100$

Similarly, for $100$, $100+1=101$

And, for $1000$, it is $1000+1=1001$
