| Direction; In the given questions, a series of letters and numbers is given the terms of which follow certain definite pattern in groups. However, some terms in the series are missing which are given in the same order as one of the options below the series Choose the correct option. |
A) 23, H, K, 0, H
B) 19, E, , R, H
C) 21, G, L, N, F
D) 17 F I, S, T
Correct Answer: A
Solution :
; We see that the series can be divided into 5 groups of four terms each. X W C _ /T S 20 _ / P 12 _ t. / 15 K _ P / _ G S 7 Observing the above series, we see that each group consists of two consecutive letters in forward or backward direction and the number represents the position of one of these letters in the English alphabet. So, 1st missing term must be the number corresponding to X or W, i.e., 24 or 23. Also, the place values of other of the two letters and the 3rd letter are the same but from the end and beginning in the English alphabet. So, the pattern is: \[X\text{ }W\text{ }C\text{ }\underset{-}{\mathop{23}}\,/T\text{ }S\text{ }20\text{ }\underset{-}{\mathop{H}}\,/P\text{ }12\text{ }\underset{-}{\mathop{K}}\,L/15K\underset{-}{\mathop{O}}\,P/\underset{-}{\mathop{H}}\,GS7.\]
