The text in the image is not fully clear due to the shadow and blur, but I can identify parts of mathematical expressions, likely dealing with sequences or series given the symbols and numbers visible. 

Here is a rough interpretation of the visible problems:

1. **Problem 1** appears to involve calculating the sum or value in a sequence or series where specific terms and formulas are provided.
2. **Problem 2** involves a similar structure, but with different values for terms and possibly different arithmetic progression details.
3. There are references to \( S \), which might indicate the sum of terms in a sequence, and \( d \), which likely represents the common difference in an arithmetic progression.

If you could provide further details or a clearer image, I can help solve each problem step-by-step. Alternatively, if you can type out any specific problems or terms visible, I would be glad to assist in solving them. 

Would you like assistance with these steps?

In the meantime, here are some follow-up questions that might relate to arithmetic sequences and series:
1. How do you find the \( n \)-th term in an arithmetic sequence?
2. How is the sum of an arithmetic series calculated?
3. What is the significance of the common difference \( d \) in a sequence?
4. How do geometric sequences differ from arithmetic sequences in terms of their formulae?
5. What are some common applications of sequences and series in real-world scenarios?

**Tip:** For sequences, knowing the common difference or ratio is key to solving most questions.
