Answer: The next letter in the sequence is U.
Explanation:
The given sequence consists of vertically symmetric letters: A, H, I, M, O, T. Vertically symmetric letters are those that, when divided vertically down the center, are mirror images on both sides. In uppercase, these letters include:
- A
- H
- I
- M
- O
- T
- U
- V
- W
- X
- Y
These letters remain unchanged when reflected across a vertical axis.
As aforementioned, vertically symmetric letters remain unchanged when split down the middle. After “T,” the next vertically symmetric letter is “U,” which fits the pattern.
