# Alternate Letters

When one letter is skipped between two letters, they are called alternate letters. For example, A, C, E, G, I are known as alternate letters.
Similarly, (i) K, M, O, Q, S, U; (ii) B, D, F, H, J, L are said to be alternate letters.

 After Z in the cyclic order, A will occur. So, Y and A are known as alternate letters.
