9. Y, B,
T, G, O, ?
A. N
B. M
C. L
D. K
Answer: Option-C
Explanation:The given
sequence is a combination of two series :
I. Y,T, O and II. B, G, ?
I consists of 2nd, 7th and 12th
letters from the end of the English alphabet, while
II consists of 2nd, 7th and 12th
letters from the beginning of the English alphabet.

the 12th letter from the beginning of the English alphabet, which is L.

Answer: Option-D
Explanation:
The given sequence is a combination of two series :

C, D, E, ? II. 2nd, 4th, 6th, 8th, 10th terms i.e. B, D, F, H, ?
Clearly, I consists of consecutive letters while II
consists of alternate letters. So, the missing letter in I is F, while that in
II is J. So, the missing terms i.e. 10th and 11th terms are J and F
respectively.

A. LMNO
B. MNO
C. MNOP
D. NOPQ
Answer: Option-C
Explanation: Each term
consists of consecutive letters in order. The number of letters in the terms
goes on increasing by one at each step.
Also, there is a gap of one
letter between the last letter of the first term and the first letter of the second
term; a gap of two letters between the last letter of the second term and the
first letter of the third term; and so on.
So, there should be a gap of
three letters between the last letter of the third term and the first letter of
the desired term.
