Question
In each of the following questions, a letter-number
series is given with one or more terms missing as shown by (?). Choose the missing term out of the given alternatives. ZR15, XU18, VX21, TA24, ?Solution
First letter: Z – 2 = X X – 2 = V V – 2 = T T – 2 = R Second letter: R + 3 = U U + 3 = X X + 3 = A T + 3 = D Number: 15 + 3 = 18 18 + 3 = 21 21 + 3 = 24 24 + 3 = 27
