In these sequences:7,9,14,24,25,27,28 and 7,13,18,21,25,27,28 and 1,2,6,12,15,22,28  what will be the possible answer  for the next _,_,_,_,_,_,_? Which math operation  should be used?

The sequences you provided appear to follow distinct patterns, but their rules are not immediately obvious without more context. I'll break down each sequence to identify a potential rule and determine what the next numbers might be.

### Sequence 1: \( 7, 9, 14, 24, 25, 27, 28 \)
- Differences: 
  \[
  9 - 7 = 2, \quad 14 - 9 = 5, \quad 24 - 14 = 10, \quad 25 - 24 = 1, \quad 27 - 25 = 2, \quad 28 - 27 = 1
  \]
- There seems to be a mix of differences, but it doesn’t follow an immediately obvious arithmetic or geometric rule.

### Sequence 2: \( 7, 13, 18, 21, 25, 27, 28 \)
- Differences: 
  \[
  13 - 7 = 6, \quad 18 - 13 = 5, \quad 21 - 18 = 3, \quad 25 - 21 = 4, \quad 27 - 25 = 2, \quad 28 - 27 = 1
  \]
- This sequence also has mixed differences, but they are decreasing overall.

### Sequence 3: \( 1, 2, 6, 12, 15, 22, 28 \)
- Differences: 
  \[
  2 - 1 = 1, \quad 6 - 2 = 4, \quad 12 - 6 = 6, \quad 15 - 12 = 3, \quad 22 - 15 = 7, \quad 28 - 22 = 6
  \]
- The differences are varied, but there is some repetition of values like 6.

### Identifying Patterns:
- **Sequence 1 and Sequence 2**: Both sequences end in 28 and have some small differences (like 2, 1) at the end. However, their earlier differences don’t follow a consistent arithmetic progression, suggesting a non-linear relationship.
- **Sequence 3**: This sequence seems to involve more variation but also ends in 28.

### Hypotheses for Next Numbers:
1. **Arithmetic Progression**: If we consider the average difference between numbers, we could extend each sequence by considering recent trends.
2. **Non-Linear Progression**: The sequences might involve a combination of small steps (like 1, 2) and larger jumps (like 6, 7), which would require a more complex rule.

### Predictions for Next Numbers:
- **Sequence 1**: \( 7, 9, 14, 24, 25, 27, 28, \_\_, \_\_, \_\_ \)
    - Possible continuation: \( 30, 31, 33 \) (following a small step pattern)

- **Sequence 2**: \( 7, 13, 18, 21, 25, 27, 28, \_\_, \_\_, \_\_ \)
    - Possible continuation: \( 29, 30, 32 \) (following the small step)

- **Sequence 3**: \( 1, 2, 6, 12, 15, 22, 28, \_\_, \_\_, \_\_ \)
    - Possible continuation: \( 34, 39, 45 \) (larger jumps)

### Math Operations:
- Differences between terms are a key operation (similar to finite differences).
- The sequences might involve mixed progression rules, so examining the pattern of differences helps predict the next values.

Would you like more details or explanations on the next steps? Here are 5 related questions:

1. Can we identify a more specific rule governing each sequence?
2. How would a recursive formula apply to these sequences?
3. Can we generalize the pattern for any number of terms?
4. What is the role of mixed differences in non-linear sequences?
5. Can we find a geometric or exponential relationship in these sequences?

**Tip**: To extend sequences, always check for consistent patterns in the differences or ratios, and test multiple steps.
