What is the next letter

2 3 E 4 5 I 6 8

Each letter's position in the alphabet is equal to the sum of the two numbers before it. For example, E is the 5th letter of the alphabet, and 2+3=5. I is the 9th letter of the alphabet, and 4+5=9. Thus, since 6+8=14, the next letter will be the 14th letter of the alphabet. This is the letter N.
