Letter Series MCQs with Answers & Explanations

The letters advance by 2 positions in the alphabetical order: A (1) + 2 = C (3), C (3) + 2 = E (5), E (5) + 2 = G (7). Following this, G (7) + 2 = I (9).

The sequence moves backward by 2 steps: Z (26), X (24), V (22), T (20). The next letter is 20 - 2 = 18, which corresponds to R.

Each term increases by 3 positions: B (2), E (5), H (8), K (11), N (14). Adding 3 to N (14) gives 17, which corresponds to Q.

The alphabetical positions correspond to consecutive square numbers: 1^2 = 1 (A), 2^2 = 4 (D), 3^2 = 9 (I), 4^2 = 16 (P). The next term is 5^2 = 25, which is Y.

The alphabetical positions represent consecutive prime numbers: 2 (B), 3 (C), 5 (E), 7 (G), 11 (K), 13 (M). The next prime number is 17, which corresponds to Q.

Each pair consists of consecutive letters, and each group starts 3 positions after the start of the previous group: A (1) \rightarrow D (4) \rightarrow G (7) \rightarrow J (10) \rightarrow M (13). The pair is therefore MN.

The backward differences increase by 1 at each step: Z (26) - 3 = W (23); W (23) - 4 = S (19); S (19) - 5 = N (14). The next reduction is - 6, yielding 14 - 6 = 8, which corresponds to H.

The step difference increases by 1 each time: A + 2 = C, C + 3 = F, F + 4 = J, J + 5 = O. Adding 6 to O (15) gives position 21, which corresponds to U.

The series decreases by 2 alphabetical positions at each step: 25, 23, 21, 19, 17. The next position is 17 - 2 = 15, which corresponds to O.

The first letters advance by 3: C (3), F (6), I (9), L (12). The second letters move backward by 3: X (24), U (21), R (18), O (15). The term is LO.

The step increments increase progressively: B + 2 = D, D + 3 = G, G + 4 = K, K + 5 = P. Adding 6 to P (16) results in position 22, which is V.

The sequence consists of consecutive even-positioned letters: 10, 12, 14, 16, 18. The next is 20, which is T.

This is an alternating series: the odd positions advance from the start (A, B, C, D), while the even positions retreat from the end (Z, Y, X). The 7th position is the next forward letter, D.

The first letter advances by 1: A, B, C, D, E. The second letter also advances by 1: I, J, K, L, M. Thus, the next term is EM.

The sequence adds 4 at each step: D (4), H (8), L (12), P (16), T (20). Next is 20 + 4 = 24, which corresponds to X.

The pattern alternates subtracting 3 and subtracting 4: W (23) - 3 = T (20); T (20) - 4 = P (16); P (16) - 3 = M (13); M (13) - 4 = I (9). Next is 9 - 3 = 6, which corresponds to F.

In each pair, the second letter is 3 positions ahead of the first (B + 3 = E; G + 3 = J). The first letters advance by 5 positions: B (2), G (7), L (12), Q (17), V (22). Adding 3 to V gives Y, forming VY.

The first letters increase by 4: C (3), G (7), K (11), O (15), S (19). Within each pair, the second letter is +2 from the first: S + 2 = U. The next group is SU.

The series increases by 4 positions at each step: A (1), E (5), I (9), M (13), Q (17). Adding 4 to Q (17) gives 21, which corresponds to U.
