Question

Which pattern correctly represents the relationship between the largest number of n digits and the smallest number of (n+1) digits?

Options

• Largest n-digit number - 1 = Smallest (n+1)-digit number

• Largest n-digit number + 1 = Smallest (n+1)-digit number

• Largest n-digit number × 10 = Smallest (n+1)-digit number

• Largest n-digit number ÷ 10 = Smallest (n+1)-digit number

Answer 1

Largest n-digit number + 1 = Smallest (n+1)-digit number

Explanation:

Adding 1 to the largest number of n digits always gives the smallest number of (n+1) digits. For example, 999 + 1 = 1000.
