Find the Number After 80,350: Previous Number Problem

Q: What's the difference between predecessor and successor?

A predecessor comes BEFORE (subtract 1), while a successor comes AFTER (add 1). If 80,350 is your 'previous number', then you are the successor, which means 80,351!

Q: Why is the answer 80,351 and not 80,349?

The question says 'My previous number is 80,350' - this means we need to find what comes AFTER 80,350. Since 80,350 + 1 = 80,351, that's the answer!

Q: How do I remember which operation to use?

Think of it like this: Previous = Past = Subtract and Next = Add. If someone asks 'who comes after 5?', you naturally think 6 (add 1)!

Q: Does this work with any number?

Yes! Every whole number has exactly one successor. Whether it's 1, 100, or 1,000,000 - just add 1 to get the next number in the sequence.

Q: What if the number ends in 9?

No problem! Adding 1 to numbers ending in 9 causes carrying. For example: 999 + 1 = 1,000. The same rule applies: just add 1!

My previous number is 80,350

Who am I?

Step-by-step solution

The goal is to determine the number that comes immediately after 80,350.

Step 1: Start with the provided number, which is 80,350.
Step 2: Recognize that in a sequence of consecutive integers, the number immediately following 80,350 is its successor.
Step 3: To find the successor of any number $n$ , use the formula $n + 1$ .

Now let's calculate:

Given number: $80,350$

Successor: $80,350 + 1 = 80,351$

Therefore, the number we are looking for is $80,351$ .

The correct answer is choice 1: $80,351$ .

Final Answer

$80,351$

Key Points to Remember

Common Mistakes

Avoid these frequent errors

Confusing predecessor with successor
Don't subtract 1 when asked 'who comes after' = getting 80,349 instead of 80,351! The question asks for the NEXT number, not the previous one. Always add 1 to find the successor (next number).
