@[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

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!

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!

Solve the arithmetic sequence where numbers increase by a constant difference of 9. Find the next number in the sequence and understand the underlying concept of arithmetic progression. Suitable for students in Grades 4-6.
