Solution :
Given:
DNU, ?, NXE, SCJ, XHO
In the above-given series, add 5 to the place value of each letter of the previous term to get the next term.
First letter of the series→D + 5 = I; I + 5 = N; N + 5 = S; S + 5 = X
Second letter of the series→N + 5 = S; S + 5 = X; X + 5 = C; C + 5 = H
Third letter of the series→U + 5 = Z; Z + 5 = E; E + 5 = J; J + 5 = O
So, ISZ is the missing term of the series. Hence, the fourth option is correct.
