FAQ

Everything you need to know about this question

What's the difference between successor and predecessor?

+

The successor comes after (add 1), while the predecessor comes before (subtract 1). For 7009: successor is 7010, predecessor is 7008.

Do I always just add 1 to find the successor?

+

Yes! The successor of any whole number is always that number plus 1. It's the very next counting number in sequence.

What if the number ends in 9, like 7009?

+

Just add 1 normally! When you add 1 to a number ending in 9, the 9 becomes 0 and you carry over to the next place value: 7009+1=7010 7009 + 1 = 7010 .

Can negative numbers have successors too?

+

Absolutely! The successor of any integer is that number plus 1. For example, the successor of -5 is -4.

Why are the other answer choices wrong?

+

7100 is too big (jumps by 91), 8000 is way too big (jumps by 991), and 7008 is the predecessor, not successor.
