Question 1
Find the missing term of the alphabet series: ABD, DGK, HMS, MTB, SBL, ?
Explanation
Each group's starting letter advances by an increasing gap (3, 4, 5, 6, 7): A(1), D(4), H(8), M(13), S(19); next start = 19 + 7 = 26 = Z
Within each group the internal gaps also increase: (1,2), (3,4), (5,6), (7,8), (9,10); next gaps = (11,12): Z(26) + 11 → 11 = K, K(11) + 12 = 23 = W
Missing term = ZKW
Within each group the internal gaps also increase: (1,2), (3,4), (5,6), (7,8), (9,10); next gaps = (11,12): Z(26) + 11 → 11 = K, K(11) + 12 = 23 = W
Missing term = ZKW
Question 2
AZ, GT, MN, ......, YB, EV. The value at the blank space (.....) will be:
Explanation
First letters advance by a constant gap of 6: A(1), G(7), M(13), next = 13 + 6 = 19 = S; this is consistent since S(19) + 6 = 25 = Y, and Y(25) + 6 = 31 → 5 = E
Second letters decrease by a constant gap of 6: Z(26), T(20), N(14), next = 14 - 6 = 8 = H; consistent since H(8) - 6 = 2 = B, and B(2) - 6 = -4 → 22 = V
Missing term = SH
Second letters decrease by a constant gap of 6: Z(26), T(20), N(14), next = 14 - 6 = 8 = H; consistent since H(8) - 6 = 2 = B, and B(2) - 6 = -4 → 22 = V
Missing term = SH
