[B.T.M. 2005]
D _ 6 E G P _ H J _ 12 K M B 15 _
Answer: Option D
Answer: (d)
From the alternatives, it is clear that the series can be divided into 4 groups of four terms each _ each group comprising of three letters and a number in the third place.
D _ 6 E / G P _ H / J _ 12 K / M B 15 _
studying the pairs 6E and 12K, we find that in each group, the number is one more than the number representing the position of the letter in the fourth place, in the English alphabet.
Thus, putting A = 1, B =2, ....., Y = 25, Z = 26,
we have: 2nd missing term = H + 1 = 8 + 1 = 9; 4th missing term = 15 - 1 = 14th letter = N.
Thus, the 2nd and 4th missing terms are 9 and N respectively, which are given only in (d).
