Correct Answer: QB119


Solution : Given:
MF99, OD109, ?, SZ129, UX139

Add 2 to the positional value of the first letter, subtract 2 from the positional value of the second letter, and add 10 to the positional value of the third number of each term to obtain the next term in the series –
MF99→M + 2 = O; F – 2 = D; 99 + 10 = 109→OD109
OD109→O + 2 = Q; D – 2 = B; 109 + 10 = 119→QB119
QB119→Q + 2 = S; B – 2 = Z; 119 + 10 = 129→SZ129
SZ129→S + 2 = U; Z – 2 = X; 129 + 10 = 139→UX139

So, QB119 is the missing term in the series. Hence, the fourth option is correct.
