Which of the following letter-number clusters will replace the question mark (?) in the given series to make it logically complete? FEA 40 EDZ 32 DCY 24 CBX 16 ?
BAW 8
Track each of the three letters and the number separately across the clusters.
First letters: F, E, D, C, ? decrease by one each time, so the next is B.
Second letters: E, D, C, B, ? decrease by one each time, so the next is A.
Third letters: A, Z, Y, X, ? move backward through the alphabet (A then wrapping to Z, Y, X), so the next is W.
Numbers: 40, 32, 24, 16, ? decrease by 8 each time, so the next is 16 − 8 = 8.
Combining the parts gives the cluster BAW 8.
Hence, the answer is BAW 8.
