To solve the problem, we need to identify the pattern in each sequence of letters and determine the missing letter that completes the pattern. Let's analyze each sequence step by step:
---
1) A A B B A _
- The sequence alternates between two groups: `A A` and `B B`.
- The pattern is: `A A`, `B B`, `A A`, ...
- The next group should be `B B`.
Missing letter: `B`
---
2) G H G H G _
- The sequence alternates between `G` and `H`.
- The pattern is: `G`, `H`, `G`, `H`, `G`, ...
- The next letter should be `H`.
Missing letter: `H`
---
3) E F F E F _
- The sequence repeats the pattern `E F F`.
- The pattern is: `E F F`, `E F F`, ...
- The next part of the pattern is `E F F`.
Missing letter: `F`
---
4) M M M N N _
- The sequence has groups of three identical letters followed by two identical letters.
- The pattern is: `M M M`, `N N`, ...
- The next group should be `M M M`.
Missing letter: `M`
---
5) P Q R P Q _
- The sequence repeats the pattern `P Q R`.
- The pattern is: `P Q R`, `P Q R`, ...
- The next part of the pattern is `P Q R`.
Missing letter: `R`
---
6) U U V U U _
- The sequence alternates between two `U`s and one `V`.
- The pattern is: `U U`, `V`, `U U`, ...
- The next part of the pattern is `V`.
Missing letter: `V`
---
Final Answers:
1. `B`
2. `H`
3. `F`
4. `M`
5. `R`
6. `V`
Boxed Answer:
\[
\boxed{B, H, F, M, R, V}
\]
