Letter Series MCQs with Answers & Explanations

The letters are multiples of 3 in alphabetical order: 3 (C), 6 (F), 9 (I), 12 (L), 15 (O). The next multiple is 18, which is R.

The first letters advance by 2: B (2), D (4), F (6), H (8). The middle letters decrease by 1: Z (26), Y (25), X (24), W (23). The third letters advance by 2: A (1), C (3), E (5), G (7). The term is HWG.

The sequence adds 3 positions each step: H (8) + 3 = K (11), K + 3 = N (14), N + 3 = Q (17), Q + 3 = T (20). Next is 20 + 3 = 23, which corresponds to W.

The backward differences decrease by 1 at each step: Z (26) - 7 = S (19); S (19) - 6 = M (13); M (13) - 5 = H (8). The next step subtracts 4: 8 - 4 = 4, which corresponds to D.

The letter positions double at each step: 2 \rightarrow 4 \rightarrow 8 \rightarrow 16 \rightarrow 32. Modulo 26, position 32 wraps around to 32 - 26 = 6, which corresponds to F.

The additions increase by 1 each time: G (7) + 3 = J (10); J (10) + 4 = N (14); N (14) + 5 = S (19); S (19) + 6 = Y (25). The next addition is +7: 25 + 7 = 32. Wrapping past Z (32 - 26 = 6) gives F.

The first letter steps back by 1: P, O, N, M, L. The second letter moves forward by 2: M (13), O (15), Q (17), S (19), U (21). The third letter steps back by 1: T, S, R, Q, P. This forms LUP.

The sequence consists of the English vowels written in reverse alphabetical order: U, O, I, E, A.

Each group consists of two letters separated by 3 positions (A + 3 = D; E + 3 = H). The first letter of each group advances by 4 positions: A (1), E (5), I (9), M (13), Q (17). Adding 3 to Q gives T, producing QT.

The differences between consecutive letters increase progressively: D + 2 = F, F + 3 = I, I + 4 = M, M + 5 = R. Adding 6 to R (18) results in position 24, which corresponds to X.

The first letters move backward: Z, Y, X, W, V. The second letters move forward: A, B, C, D, E. Combining them gives VE.

The series advances by 3 at each step: K (11), N (14), Q (17), T (20), W (23). Adding 3 to W (23) yields 26, which corresponds to Z.

The pattern adds an increasing difference: E (5) + 2 = G (7); G (7) + 3 = J (10); J (10) + 4 = N (14); N (14) + 5 = S (19). Next is 19 + 6 = 25, which corresponds to Y.

Each group consists of two consecutive letters. The gap between successive groups is 2 letters (skipping CD, then GH, then KL). After MN, skipping OP leads to QR.

The letters move backward by 3 positions: R (18), O (15), L (12), I (9), F (6). Next is 6 - 3 = 3, which corresponds to C.

The first letters advance by alternating steps of +3 and +4: D (4) + 3 = G (7); G (7) + 4 = K (11); K (11) + 3 = N (14); N (14) + 4 = R (18). Each pair spans 2 letters: R + 2 = T. Thus, the term is RT.

The series adds 4 to each consecutive letter position: 2 (B), 6 (F), 10 (J), 14 (N), 18 (R). The next position is 18 + 4 = 22, which corresponds to V.

The differences between consecutive letters increase by 1 each time: +1, +2, +3, +4. Next is +5: K (11) + 5 = 16, which corresponds to P.

The sequence consists of consecutive 3-letter alphabetical triplets without gaps: BCD (2, 3, 4), EFG (5, 6, 7), HIJ (8, 9, 10), followed by KLM (11, 12, 13).

The sequence subtracts 4 positions at each step: W (23), S (19), O (15), K (11), G (7). Subtracting 4 from 7 yields position 3, which corresponds to C.
