Key Points to Remember

Essential concepts to master this topic
  • Predecessor Rule: Subtract 1 from given number to find previous
  • Successor Method: Add 1 to 92001 gives 92002 as next number
  • Verification Check: Count forward: 92000 → 92001 → 92002 follows consecutive pattern ✓

Common Mistakes

Avoid these frequent errors
  • Subtracting or adding 10 instead of 1
    Don't subtract 10 from 92001 to get 92000 - 10 = 91991! This confuses place value patterns with basic counting. Always add or subtract exactly 1 to find consecutive numbers in a sequence.

FAQ

Everything you need to know about this question

Why is the answer 92000 and not 92000?

+

The predecessor of 92001 92001 is found by subtracting 1: 92001 - 1 = 92000. This follows the basic counting sequence where each number is exactly 1 more than the previous.

How do I remember which operation to use?

+

Previous number: subtract 1
Next number: add 1
Think of it like counting backwards or forwards by ones!

What if the number ends in 1 like 92001?

+

It doesn't matter what digit the number ends with! Always subtract 1 for previous and add 1 for next. So 92001 - 1 = 92000 and 92001 + 1 = 92002.

Can I check my answer by counting?

+

Yes! Count up from your first number: 92000, 92001, 92002. If each number increases by exactly 1, you have the right sequence.

What about larger numbers like 99999?

+

The same rule applies! 99999+1=100000 99999 + 1 = 100000 . Don't worry about how many digits change - just add or subtract 1 as normal.
