Solution (c): The logic followed here is as follows:

T –2 R –2 P –2 N –2 L
D +3 G +3 J +3 M +3 P

+2 +2 +2 +2
E G I K M
Therefore, "NMK" is the missing term.
Example 3: Which number would replace question mark in the series?

7, 12, 19, ?, 39
(a) 29 (b) 28

(c) 30 (d) 32
Solution (b): The given sequence follows the pattern: + 5, +7, +9... i.e., 7+5=12, 12+7=19

Missing number = 19+9= 28.

Hence, the answer is (b).
Example 4: In following letter series, some of the letters are missing which are given in that order as one of
the alternatives below it. Choose the correct alternative.
(a) bbca (b) acba
(c) cabc (d) cacc

Solution (a): We can observe that pattern bcab is repeated.
Hence, option (a) is correct.
