Q1. What will come in place of the question mark (?) in the following number series?
5, 4, 6, 15, 56, ?
5 x 1 – 1 = 4
4 x 2 – 2 = 6
6 x 3 – 3 = 15
15 x 4 – 4 = 56
56 x 5 – 5 = 275
Q2. What will come in place of the question mark (?) in the following number series?
2, 4, 12, 16, 80, ?
2 + 2 = 4
4 x 3 = 12
12 + 4 = 16
16 x 5 = 80
80 + 6 = 86
Q3. What will come in place of the question mark (?) in the following number series?
15, 16, 24, 51, 115, ?
The next difference will be 5x5x5 = 125.
So, 115 + 125 = 240.
Q4. What will come in place of the question mark (?) in the following number series?
12, 7, 9, 16.5, 37, ?
12 x 0.5 + 1 = 7
7 x 1 + 2 = 9
9 x 1.5 + 3 = 16.5
16.5 x 2 + 4 = 37
37 x 2.5 + 5 = 97.5
Q5. What will come in place of the question mark (?) in the following number series?
5, 15, 30, 55, 95, ?
The gap between those differences grows by 5 each time: 5, 10, 15…
So the next gap is 20, making the next difference 60 (40 + 20).
Finally, 95 + 60 = 155.
Q6. Find the wrong number in the following series.
10, 14, 23, 48, 95, 218
If we add 49 to 48, it should be 97 (not 95).
Then 97 + 121 gives the last number, 218. So 95 is wrong.
Q7. Find the wrong number in the following series.
4, 9, 20, 43, 90, 186
4 x 2 + 1 = 9
9 x 2 + 2 = 20
20 x 2 + 3 = 43
43 x 2 + 4 = 90
90 x 2 + 5 = 185. Therefore, 186 is wrong.
Q8. Find the wrong number in the following series.
200, 98, 48, 21.5, 8.75
(200 / 2) – 2 = 98
(98 / 2) – 2 = 47. Here, 48 is given which is incorrect.
Let’s check the next one: (47 / 2) – 2 = 21.5. This fits perfectly.
Q9. Find the wrong number in the following series.
2, 2, 6, 32, 210, 1890
2 x 1 = 2
2 x 3 = 6
6 x 5 = 30 (Not 32!)
30 x 7 = 210
210 x 9 = 1890. So, 32 is wrong.
Q10. Find the wrong number in the following series.
10, 10, 13, 22, 36, 60
10 + 0 = 10
10 + 3 = 13
13 + 8 = 21 (Not 22!)
21 + 15 = 36
36 + 24 = 60. So, 22 is wrong.
