Correct
Solution: Option (b)
Explanation:
If we observe the given series, we find that it’s a combination of two series.
So, the missing term = (41 × 3) – 1 = 123 – 1 = 122
Hence, option (b) is the correct answer.

Question 2 of 5
2. Question
Consider the sequence given below:
7/12/91, 2/1/92, 28/1/92, 23/2/92, ….
What is the next term of the series?
Correct
Answer: C
Explanation:
7/12/91 is considered as 7th December 91
2/1/92 is considered as 2nd January 92
The difference between the above 2 dates is 25, 26th day as the next number.
28/1/92 add 26 days and 26th day is 23/2/92
92 is a leap year. it has 29 days in February.
So, the next date must be 20/3/92. Hence option (c) is correct answer.

Question 3 of 5
3. Question
A simple mathematical operation in each number of the sequence 5, 10, 26, 50, 121, 170, … results in a sequence with respect to prime numbers. Which one of the following is the next numbers in the sequence?
Correct
Answer: D
Explanation:
(Prime Number)2 + 1 = Sequence N
22 + 1 = 5
32 + 1 = 10
52 + 1 = 26
72 + 1 = 50
112 + 1 = 122
132 + 1 = 170
172 + 1 = 290
So, 192 + 1 = 362 Hence option (d) is correct answer.
Incorrect
Answer: D
Explanation:
(Prime Number)2 + 1 = Sequence N
22 + 1 = 5
32 + 1 = 10
52 + 1 = 26
72 + 1 = 50
112 + 1 = 122
132 + 1 = 170
172 + 1 = 290
So, 192 + 1 = 362 Hence option (d) is correct answer.

Question 4 of 5
4. Question
What is value of X in the sequence
383 394 407 414 419 X
Correct
Answer: A
Explanation:
Series Pattern Given Series
383 383
383 + (8 + 3) = 394 394
394 + (9 + 4) = 407 407
407 + (0 + 7) = 414 414
414 + (1 + 4) = 419 419
419 + (1 + 9) = 429 429 Hence, option (a) is the correct answer.
Incorrect
Answer: A
Explanation:
Series Pattern Given Series
383 383
383 + (8 + 3) = 394 394
394 + (9 + 4) = 407 407
407 + (0 + 7) = 414 414
414 + (1 + 4) = 419 419
419 + (1 + 9) = 429 429 Hence, option (a) is the correct answer.

Question 5 of 5
5. Question
Find the tenth term of the series 13, 8, 3, -2 …?
Correct
Answer: C
Explanation:
First term, a = 13
Common Difference, d = Second Term – First Term = 8 – 13 = -5
The nth term is given by the formula Tn = a +(n-1)d
Tenth term, T10= a + (n-1) d = 13 + (10 -1) (-5) = 13 – 45 = – 32
Hence, option (c) is the correct answer.
Incorrect
Answer: C
Explanation:
First term, a = 13
Common Difference, d = Second Term – First Term = 8 – 13 = -5
The nth term is given by the formula Tn = a +(n-1)d
Tenth term, T10= a + (n-1) d = 13 + (10 -1) (-5) = 13 – 45 = – 32
Hence, option (c) is the correct answer.
