What is the next number in the series 45, 15, 30, 30, 10,20

To determine the next number in the series \(45, 15, 30, 30, 10, 20\), let's analyze the pattern:

- **Step 1**: The first term is \(45\).
- **Step 2**: The second term \(15\) is obtained by dividing \(45\) by 3.
- **Step 3**: The third term \(30\) is obtained by multiplying \(15\) by 2.
- **Step 4**: The fourth term \(30\) remains the same.
- **Step 5**: The fifth term \(10\) is obtained by dividing \(30\) by 3.
- **Step 6**: The sixth term \(20\) is obtained by multiplying \(10\) by 2.

Following this observed sequence:
- We divide by 3, multiply by 2, repeat the same term, divide by 3, and multiply by 2.

To continue:
- **Next Step**: We divide \(20\) by 3, which gives approximately \(6.67\).

So, the next term in the series would likely be:

\[
6.67
\]

Here are some additional questions you may find interesting:
1. What if we multiplied or divided differently in the sequence?
2. Can we form a similar sequence with different initial values?
3. How would the sequence change if we added a repeating addition or subtraction step?
4. How might rounding influence sequences with non-integer values?
5. What are other methods to predict patterns in sequences?

**Tip**: For number sequences, check for common operations like addition, subtraction, multiplication, and division.
