Which of the following terms will replace the question mark (?) in the given series?
HDLB, LBPZ, PZTX, ? , XVBT
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. TXXV.
Given series: HDLB, LBPZ, PZTX, ? , XVBT
H + 4 = L; L + 4 = P; P + 4 = T; T + 4 = X;
D - 2 = B; B - 2 = Z; Z - 2 = X; X - 2 = V;
L + 4 = P; P + 4 = T; T + 4 = X; X + 4 = B;
B - 2 = Z; Z - 2 = X; X - 2 = V; V - 2 = T
Hence, the missing term is TXXV.
