Which should come next at the end of this row of letter's E I L?

Based on the pattern observed in the given sequence of letters (E, I, L), the next letter should be P. This is because each letter is moving forward in the alphabet by two positions: E (+2) = G, G (+2) = I, I (+2) = K, and K (+2) = M. Therefore, following this pattern, the next letter after L would be P.
