Question 58

What does “successor” mean?
It is the number that comes right after a given number on the number line.

Rule:
To find the successor, add \(1\) to the number.

If the integer is \(n\), then:

\(n\) + \(1\)

= \(n + 1\)

Examples:

• For \(-3\): \(-3\) + \(1\) = \(-2\)
• For \(0\): \(0\) + \(1\) = \(1\)
• For \(7\): \(7\) + \(1\) = \(8\)

So, the successor of any integer \(n\) is \(n + 1\).
