Solution :
Given:
ALZ, CJV, EHR, GFN, ?
In the given series, add 2 to the place value of the first letter, subtract 2 from the place value of the second letter, and subtract 4 from the place value of the third letter of the previous term to obtain the next term.
ALZ→A + 2 = C; L – 2 = J; Z – 4 = V
CJV→C + 2 = E; J – 2 = H; V – 4 = R
EHR→E + 2 = G; H – 2 = F; R – 4 = N
GFN→G + 2 = I; F – 2 = D; N – 4 = J
So, the missing term in the series is IDJ. Hence, the third option is correct.
