3. Obtain the missing term
B, G, K, ?
a) N
b) P
c) M
d) L
Answer: a
Explanation: The series is defined by the 2nd , 7th , 11th term of the alphabet. Hence, the next term would be the 14th term i.e., N.
Option (a) is the correct answer.

4. 7,15, 27, ?, 63
a) 42
b) 43
c) 38
d) none of these
Answer: b
Explanation: The series follows a pattern of +8, +12, +__, +20. Obviously we need to add 16 for the missing term. Hence, 43 i.e., option (b) is the correct answer

5. ?, 425, 600, 825, 1100, 1425
a) 225
b) 300
c) 250
d) none of these
Answer: b
Explanation: The series follows a pattern of +175, +225, +275, +325. Hence, the first term should be 300, so the answer is option (b).

8. 31, 32, 36, 45, ?
a) 55
b) 56
c) 61
d) 62
Answer: c
Explanation: +1, +4, +9, thus +16 and hence the next term should be 61. Correct answer is option (c)

9. 1, 5, 2, 25, 3, 125, 4, ?
a) 144
b) 36
c) 625
d) 500
Answer: c
Explanation: There are two series intermixed with one another. One of the series is placed at the odd places of the series and the other is placed at the even places. The series at the even places of the series is 5, 25, 125 and hence its next term should be 625. Option (c) is correct answer
