Let's solve the problems shown in the image:

### Problem 25:
**Arrange the numbers and symbols of the following and choose the correct answer:**
\[ 1, 2, 3, +, - \]

We need to find an arrangement of these numbers and symbols that forms a valid equation.

Possible solution:  
\[ 1 + 2 = 3 \]
This means \( 1 + 2 = 3 \) is the correct equation.

So, the answer is **3**.

### Problem 26:
**Arrange the numbers and symbols of the following and choose the correct answer:**
\[ 2, 3, 4, +, - \]

Possible solution:
\[ 4 - 2 = 2 \] or \[ 3 + 2 = 5 \]
Since neither of these results match any of the choices, let's try different combinations.

\[ 4 - 3 = 1 \] 
The possible answer is **1**.

### Problem 27:
**What is the next number in the sequence: 3, 6, 10, 15,...?**

Looking at the sequence:
- The difference between consecutive terms is increasing by 1 each time:
  - \( 6 - 3 = 3 \)
  - \( 10 - 6 = 4 \)
  - \( 15 - 10 = 5 \)

So, the next difference should be \( 6 \).
- \( 15 + 6 = 21 \)

The answer is **21**.

### Follow-up Questions:
1. Can you find another valid equation for the set \( 1, 2, 3, +, - \) besides \( 1 + 2 = 3 \)?
2. What are other possible equations for the set \( 2, 3, 4, +, - \) that might not be in the given options?
3. How can you derive the formula for the sequence in Problem 27?
4. Can you identify a sequence where the difference between terms decreases instead of increasing?
5. How would the pattern change if the increment between sequence terms was by a different constant number?

### Tip:
When identifying patterns in sequences, try to find a consistent difference or ratio between consecutive terms first.

Arrange the numbers and symbols to form correct equations and identify the next number in the sequence.
