Step-by-step solution

To solve this problem, we'll follow these steps:

  • Step 1: Identify the increment between the given sequence numbers.
  • Step 2: Use this increment to find the next numbers in the sequence.

Let's work through each step:

Step 1: Identify the increment.
The sequence begins with 582,985 582,985 and 583,985 583,985 . Calculate the difference between these numbers:
583,985582,985=1,000 583,985 - 582,985 = 1,000 .
Thus, each number in the sequence increases by 1,000.

Step 2: Extend the sequence.
Starting from the last given number 583,985 583,985 , add 1,000 to find the subsequent numbers:

  • The next number is 583,985+1,000=584,985 583,985 + 1,000 = 584,985 .
  • The following number is 584,985+1,000=585,985 584,985 + 1,000 = 585,985 .
  • Continue this process: 585,985+1,000=586,985 585,985 + 1,000 = 586,985 .

Therefore, by continuing the arithmetic pattern, the completed sequence is:
584,985,585,985,586,985 584,985, 585,985, 586,985 .

Matching this result with the given choices, the correct answer is choice 3, which is:
584,985,585,985,586,985 584,985, 585,985, 586,985 .

Final Answer

584,985, 585,985, 586,985 584{,}985,\ 585{,}985, \ 586{,}985

Key Points to Remember

Essential concepts to master this topic
  • Pattern Recognition: Find the common difference between consecutive terms
  • Technique: Subtract first from second: 583,985582,985=1,000 583,985 - 582,985 = 1,000
  • Check: Each new term equals previous term plus 1,000 ✓

Common Mistakes

Avoid these frequent errors
  • Adding a small increment like 1 or 10
    Don't assume the pattern increases by 1 or 10 just because it's a sequence = wrong numbers! This ignores the actual difference calculation. Always subtract the first term from the second term to find the true increment.

FAQ

Everything you need to know about this question

How do I know what number to add each time?

+

Always subtract the first number from the second number in the sequence. In this case: 583,985582,985=1,000 583,985 - 582,985 = 1,000 , so you add 1,000 each time.

What if the numbers are really big like these?

+

Big numbers work exactly the same way! Focus on the difference between them, not their size. The pattern is what matters, not how large the numbers are.

Could the sequence go down instead of up?

+

Yes! If the second number is smaller than the first, you'd subtract the same amount each time. Always check which direction the pattern goes.

How many numbers should I find in the sequence?

+

Look at what the question asks for! Usually it wants the next 3 numbers after the given ones. Keep adding the common difference until you have enough.

What if I get confused with the commas in large numbers?

+

Focus on the numerical value, not the commas. 582,985 582,985 is just 582985. The commas help us read it, but don't affect the math.
