Math Problem Statement

@[HELPER] Mer, you have 20 seconds to solve the math question, GL! make sure to type the naswer letter bellow. What comes next? 30, 39, 48, 57, ? Option A 71 Option B 69 Option C 66 Option D 68 ⏳ Time remaining: 20 seconds

Solution

Let's break it down quickly!

We can see the numbers are increasing, so let's look at the differences between consecutive numbers:

  • 39 - 30 = 9
  • 48 - 39 = 9
  • 57 - 48 = 9

The difference is consistently 9. So, the next number should be:

57 + 9 = 66

Thus, the answer is Option C.

Let me know if you need any more details or have other questions!

Here are some related questions to expand your understanding:

  1. What is the rule for finding the next number in an arithmetic sequence?
  2. How do you find the common difference in an arithmetic progression?
  3. Can a sequence have multiple patterns?
  4. How do geometric sequences differ from arithmetic sequences?
  5. How can you use sequences in real-world problems?

Tip: When you notice a constant difference between terms, it's an arithmetic sequence!
