Observe the first letter of each cluster: B(2), H(8), N(14), T(20). Since each increases by 6, the next is 20 + 6 = 26 (Z).
Observe the first letter of each cluster: B(2), H(8), N(14), T(20). Since each increases by 6, the next is 20 + 6 = 26 (Z).
Analyze the starting letter of each cluster
The series starts with: B(2), H(8), N(14), T(20). The pattern is +6. Therefore, the next start letter is 20 + 6 = 26, which is Z.
Analyze the internal sequence of each cluster
Each cluster follows a +2, +2 increment (e.g., B+2=D, D+2=F). Following this pattern from Z: Z+2 = 26+2 = 28. Since 26 is Z, 27 is A, and 28 is B. Then B+2 = D. The next cluster is ZBD.
B: YAC is incorrect because the start letter Y does not follow the +6 increment pattern. C: XAB is incorrect as X is the 24th letter, failing the +6 pattern from T(20). D: ZAC is incorrect because it uses the wrong second letter progression (A instead of B).
A is correct because the series follows a consistent +6 increment for the first letter (B, H, N, T → Z) and a +2, +2 increment for all internal letters within each cluster.
For alphabetical series, always convert letters to their numerical positions (A=1, B=2... Z=26) first to identify mathematical patterns quickly.
