Correct Answer: UDEX
Solution :
Given:
ABCD, FVJV, KPQN, PJXF, ?
Add 5 and 7 in the place value of the first and the third letters and subtract 6 and 8 from the place value of the second and fourth letters of the previous term to obtain the next term.
ABCD→A + 5 = F; B – 6 = V; C + 7 = J; D – 8 = V→FVJV
FVJV→F + 5 = K; V – 6 = P; J + 7 = Q; V – 8 = N→KPQN
KPQN→K + 5 = P; P – 6 = J; Q + 7 = X; N – 8 = F→PJXF
PJXF→P + 5 = U; J – 6 = D; X + 7 = E; F – 8 = X→UDEX
So, UDEX is the missing term in the given series. Hence, the third option is correct.
