Answer

To solve the problem of filling the blanks in the sequence `pqr` _ _ `rs prs` _ _ `spq` _ , we will follow a systematic approach.

### Step-by-Step Solution:

1. **Identify the given sequence**: We have `pqr` followed by two blanks, then `rs prs`, followed by two blanks, and finally `spq` followed by one blank.

2. **Recognize the pattern**: The letters involved are P, Q, R, and S. We need to determine how these letters are arranged in the blanks.

3. **Fill the first two blanks**: After `pqr`, we need to fill the two blanks. The next part is `rs prs`. If we look at the letters, we can see that after `pqr`, the next logical sequence would be to continue with the next letters in the cyclic order of P, Q, R, S. Therefore, we can fill the first two blanks with `s` and `p` to make it `pqr s p`.

4. **Fill the next two blanks**: Now we have `rs prs`. The next part is `spq`. To maintain the cyclic order, we can fill the two blanks after `rs prs` with `q` and `r`. So it becomes `rs prs q r`.

5. **Fill the last blank**: Finally, we have `spq` followed by one blank. Continuing the cyclic order, after `spq`, the next letter would be `r`. Thus, we fill the last blank with `r`.

6. **Final sequence**: Combining all the filled parts, we get the complete sequence as `pqr s p rs prs q r spq r`.

### Final Answer:
The filled sequence is: `pqr s p rs prs q r spq r`.
