Alphabets	A	B	C	D	E	F	G	H	I	J	K	L	M
Positional value	1	2	3	4	5	6	7	8	9	10	11	12	13
Positional value	26	25	24	23	22	21	20	19	18	17	16	15	14
Alphabets	Z	Y	X	W	V	U	T	S	R	Q	P	O	N

The pattern/logic followed here is:
L + 2 = N; N + 3 = Q; Q + 4 = U; U + 5 = Z
B + 3 = E; E + 4 = I; I + 5 = N; N + 6 = T
X + 4 = B; B + 5 = G; G + 6 = M; M + 7 = T
Hence, ZTT will complete the incomplete series.
