The next two letters are likely C & U. There are at least 2 patterns in these letters. FIrst is the list of vowels that make up every other letter. Then the letters alternate from the ends of the alphabet. If there is a Z, a B, then a Y, then C would likely be next, and then X. But there would be whatever vowel in sequence next.
The answer is c, as you can see, though it is irrelevant, the letters a e i o... are all vowels, between them go the letters of alphabet backwards then forwards, z , b( because a has already been used), and y which comes before z... the next letter will be c which is after b, and after that would u.
