Question 1
Examine this series: 3, 4, 10, 33, 136. If another series is written with the same rule, what number would come in the place E: 7, A, B, C, D, E ?
1160
920
1165
840
Ans: c
The number 1165 will come in place of (E). 4 = 3 X 1 + 1, then 4 X 2 + 2 = 10, then 10 X 3 + 3 = 33, then 33 X 4 + 4 = 136. Similarly, A = 7 X 1 + 1 = 8, B = 8 X 2 + 2 = 18, C = 18 X 3 + 3 = 57, then D = 57 X 4 + 4 = 232, E = 232 X 5 + 5 = 1165.

Question 3
In the following number series, one of the numbers does not fit into the series. Find the wrong number.
5, 7.5, 11.25, 17.5, 29.75, 50, 91.25
7.5
17.5
29.75
91.25
Ans: c
Number 29.75 is wrong and should be replaced by 28.75 . The series is: 5 + (1.25 X 2) gives 7.5, 7.5 + (1.25 X 3) gives 11.25, then 11.25 + (1.25 X 5) gives 17.5, then 17.5 + (1.25 X 9) gives 28.75, then 28.75 + (1.25 X 17) gives 50, then 50 + (1.25 X 33) gives 91.25. The multipliers of 1.25 increase by 1, 2, 4, 8, 16
Question 4
One number is wrong in the series. Find the wrong number.
2, 3, 9, 27, 112, 565, 3396
Question 5
Two numbers of the following series have been put inside round brackets. Study the series and pick your answer from the four choices given below.
(2), 5, (12), 25, 41, 61
if the terms in both the brackets are right.
if the term in the first bracket is right but the term in the second bracket is wrong.
if the term in the first bracket is wrong but the term in the second bracket is right.
if the terms in both the brackets are wrong.
Ans: d
Both the bracket terms are wrong. Numbers 2 and 12 should be replaced by number 1 and 13 respectively, so that the series successively moves with difference of 4, 8, 12, 16, 20.
