Which of the following letter clusters will replace the question mark (?) in the given series to make it logically complete?
KGB, JFA, IEZ, HDY,?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. GCX.
Given series: KGB, JFA, IEZ, HDY,?
K - 1 = J, J - 1 = I, I - 1 = H, H - 1 = G
G -1 = F, F - 1 = E, E - 1 = D, D - 1 = C
B - 1 = A, A - 1 = Z, Z - 1 = Y, Y - 1 = X
So, the next term in the series is GCX.
