Find the next term in the series: B2, K12, T72, ___
AA434
BA432
CC432
DC434
Answer & Solution
Correct answer: C. C432
1. Letters: B(2), K(11), T(20) increase by 9 each; next 20+9 = 29 → wraps to C (29 − 26 = 3).
2. Numbers: 2, 12, 72 multiply by 6 each; next = 72 × 6 = 432.
3. So the next term is C432.
