Logical Reasoning - Number and Letter Series
- Option : A
- Explanation : The series is A + 2 = C, C + 2 = E, E + 2 = G; G + 2 = I, I + 2 = K. The missing letter is I.
- Option : A
- Explanation : The series is +1, +2, +3, +4, +5 and so on. A + 1 = B; B +2 = D; D + 3 = G; G + 4 = K; K + 5 = P. The missing letter is K.
- Option : C
- Explanation : The series is +3. The missing letter is N + 3 = Q.
Alternative solution: Skip two letters to get the next letter, i.e., skip O and P after N to get Q. The missing letter is Q.
- Option : D
- Explanation : This series is formed by moving +2 and +3
for each pair of letters starting from left. Thus, the
missing letter is N + 3 = Q.
Alternative solution: Skip one and two letters alternately to get the next letter, i.e., skip two letters O and P after N to get Q.
- Option : A
- Explanation : B = 2, ... K = 11 according to the alphabet series. Thus, the alphabet series have been constructed according to the prime numbers. The next prime number is 13 and the corresponding letter is M.
