Correct Answer: NNLJ
Solution :
Given:
NDRF, NZJT, NVBH, NRTV, ?
The first letter of each term is the same.
Subtract 4 and 8 from the place value of the second and third letters respectively, and add 14 to the place value of the fourth letter of the previous term to get the next term in the series.
NDRF→N; D – 4 = Z; R – 8 = J; F + 14 = T→NZJT
NZJT→N; Z – 4 = V; J – 8 = B; T + 14 = H→NVBH
NVBH→N; V – 4 = R; B – 8 = T; H + 14 = V→NRTV
NRTV→N; R – 4 = N; T – 8 = L; V + 14 = J→NNLJ
So, NNLJ is the missing term of the series. Hence, the third option is correct.
