Olympiad Test: Alphabet Test - 2 - Class 6 MCQ

The second and fourth letters in the series, L and A, are static. The first and third letters consist of an alphabetical order beginning with the letter E.

There is a gap of four letters between the first and second, the second and third letters of each term, and also between the last letter of a term and the first letter of the next term.

This is an alternating series in alphabetical order. The middle letters follow the order ABCDE. The first and third letters are alphabetical beginning with J. The third letter is repeated as the first letter in each subsequent three-letter segment.

This series consists of a simple alphabetical order with the first two letters of all segments: B, C, D, E, F, G, H, I, J, K. The third letter of each segment is a repetition of the first letter.

The given series may be divided into 2 groups: I. A, B, C, D, E, F, ?, ? and II. N, O, P, ?
Clearly, the given series consists of two terms of I followed by one term of II.
The missing terms in I are G and H while the missing term in II is Q.

The given sequence is a combination of two series: I. 1st, 3rd, 5th, 7th, 9th, 11th terms i.e. A, B, C, D, E, ? II. 2nd, 4th, 6th, 8th, 10th terms i.e. B, D, F, H, ?
Clearly, I consist 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.

The number of letters in the terms of the given series increases by one at each step.
The first letter of each term is two steps ahead of the last letter of the preceding term.
However, each term consists of consecutive letters in order.

The given sequence is a combination of two series:
I. D, H, L and II. W, S, ?
I consists of every fourth letter from the beginning  of the English alphabet while II consists of every fourth letter from the end of the English alphabet.
So, the missing letter in II is the third 4th letter from the end of the English alphabet, which is O.

The series may be divided into groups as shown:
b e d / f ? h / j ? l
Clearly in the first group, the second and third letters are respectively three and two steps ahead of the first letter. A similar pattern would follow in the second and third groups.

There are three series to look for here. The first letters are alphabetical in reverse: Z, Y, X, W, V. The second letters are in alphabetical order beginning with A. The number series is as follows: -1, + 2, -3, + 4...... i.e. 5 – 1 = 4
4 + 2 = 6
6 – 3 = 3
3 + 4 = 7
