Which sequence do you get when you start to add the All 1's sequence up ? What sequence do you get when you add the all 1's sequence up and down?

Let's break this into two parts:

### 1. Adding the "All 1's" sequence up (cumulative sum):
The "All 1's" sequence is simply \( 1, 1, 1, 1, 1, \ldots \). If you keep adding these values together, you get the cumulative sum:

\[
1, 2, 3, 4, 5, 6, \ldots
\]

This is called the **natural numbers sequence**.

### 2. Adding the "All 1's" sequence up and down (difference of sums):
If you add the "All 1's" sequence in a back-and-forth manner, summing up and then subtracting repeatedly, you are essentially alternating between adding and subtracting 1. This forms a sequence like:

\[
1, 0, 1, 0, 1, 0, \ldots
\]

This alternating sequence is known as the **alternating binary sequence**.

### Summary:
- **Adding the All 1's sequence up** gives the sequence \( 1, 2, 3, 4, 5, 6, \ldots \) (natural numbers).
- **Adding the All 1's sequence up and down** gives the sequence \( 1, 0, 1, 0, 1, 0, \ldots \) (alternating binary sequence).

Would you like any further details or have specific questions?

Here are 5 related questions:
1. How do you define the cumulative sum of any sequence?
2. What are the properties of the natural numbers sequence?
3. What is the significance of alternating sequences in number theory?
4. How would the result change if you used a different starting sequence, like all 2's?
5. Can you visualize these sequences on a graph?

**Tip**: Alternating sequences are common in many mathematical and engineering applications, especially in signal processing!

Which sequence do you get when you start to add the All 1's sequence up? What sequence do you get when you add the all 1's sequence up and down?

Discover the sequence resulting from adding the 'All 1's' sequence, leading to the natural numbers sequence, and the alternating binary sequence when adding and subtracting 1 in a back-and-forth pattern. This problem touches on cumulative sums, alternating sequences, and number theory, ideal for students in Grades 9-12.
