Q-1) What should come in place of the question mark (?) in the following number series?
5, 10, 13, 26, 29, 58, ?, 122
(a)
(b)
(c)
(d)
(e)
Add 3 after doubling the previous number.
Q-2) What should come in place of the question mark (?) in the following number serie?
3, 7, 13, ?, 31, 43
(a)
(b)
(c)
(d)
(e)
The given number series is based on the following pattern:
7 + 6 = 13
13 + 8 = 21
21 + 10 = 31
31 + 12 = 43
Hence, the number 21 will replace the question mark.
Q-3) What should come in place of the question mark (?) in the following number series?
64, 54, 69, 49, 74, 44, ?
(a)
(b)
(c)
(d)
(e)
The series is as follows:
64 + 5 = 69;
69 + 5 = 74;
74 + 5 = 79
54 – 5 = 49;
49 – 5 = 44
Q-4) A wrong number is given in the following number series. Find out that wrong number.
16, 19, 21, 30, 46, 71, 107
(a)
(b)
(c)
(d)
(e)
The series is based on the following pattern :
16 + $1^2$ = 17; not 19
17 + $2^2$ = 21
21 + $3^2$ = 30
30 + $4^2$ = 46
46 + $5^2$ = 71
71 + $6^2$ = 107
Clearly, 19 should replaced by 17.
Q-5) What should come in place of the question mark (?) in the following number series?
1, 8, 9, ?, 25, 216, 49
(a)
(b)
(c)
(d)
(e)
Can you see that the pattern is
$1^2$, $2^3$, $3^2$, $4^3$, $5^2$, $6^3$, $7^2$
Q-6) A wrong number is given in the following number series. Find out that wrong number.
7, 9, 16, 25, 41, 68, 107, 173
(a)
(b)
(c)
(d)
(e)
The series is based on the following pattern :
7 + 9 = 16
9 + 16 = 25
16 + 25 = 41
25 + 41 = 66; 68
41 + 66 = 107
66 + 107 = 173
Clearly, 68 should be replaced by 66
Q-7) What should come in place of the question mark (?) in the following number series?
29, 23, ?, 17, 13, 11, 7
(a)
(b)
(c)
(d)
(e)
This is a series of prime numbers :
Q-8) What should come in place of the question mark (?) in the following number serie?
102, 104, 99, 97, 106, ?
(a)
(b)
(c)
(d)
(e)
The series is as follows
Q-9) What should come in place of the question mark (?) in the following number series?
336, 210, 120, ?, 24, 6, 0
(a)
(b)
(c)
(d)
(e)
Note that
0 = $1^3$ – 1
6 = $2^3$ – 2
24 = $3^3$ – 3
Q-10) Only one number is wrong in the following number series. Find out the wrong number.
19, 68, 102, 129, 145, 154
(a)
(b)
(c)
(d)
(e)
The series is + $(7)^2$, + $(6)^2$, + $(5)^2$, + $(4)^2$, + $(3)^2$
The wrong number is 102.
It should be 68 + $(6)^2$ = 104
