Correct Answer: FBT
Solution :
Given:
PHD, TZU, XRL, BJC, ?
Add 4 to the place value of the first letter and subtract 8 and 9 from the place value of the second and third letters respectively of the previous term to get the next term in the series.
PHD→P + 4 = T; H – 8 = Z; D – 9 = U→TZU
TZU→T + 4 = X; Z – 8 = R; U – 9 = L→XRL
XRL→X + 4 = B; R – 8 = J; L – 9 = C→BJC
BJC→B + 4 = F; J – 8 = B; C – 9 = T→FBT
So, FBT is the missing term. Hence, the second option is correct.
