48, 54, 63, 81 and 105 are divisible by 3 but not 35.
The given series follows the pattern that,
18, 97, 26, 91, ?, 83
=> 18 + 8 = 26
=> 97 - 8 = 91
=> 26 + 8 = 34
=> 91 - 8 = 83
Hence, the missing number is 34.
1 x 1 + 1 x 1 = (1 + 1) = 2
2 x 2 + 2 x 2 = (4 + 4) = 8
8 x 3 + 3 x 3 = (24 + 9) = 33
33 x 4 + 4 x 4 = (132 + 16) = 148
148 x 5 + 5 x 5 = (740 + 25) = 765.
Given
6 3 3 6 24 ?
Here
6
6 x 0.5 = 3
3 x 1 = 3
3 x 2 = 6
6 x 4 = 24
24 x 8 = 192
The next number in the given series is 192.
All except Parrot are birds of prey.
Except 437 all others are prime numbers.
The series given follow the pattern
+2, +2+4, +2+4+6, +2+4+6+8, +2+4+6+8+10,...
Here ? = 7 + 2 + 4 = 13.
The given series is 1 6 27 124 650
1
1 + 2 x 2 = 6
6 + 3 x 3 = 27
27 + 4 x 4 = 124
124 + 5 x 5 = 645 (NOT 650)
Hence, the odd man in the given number series is 650.
4 30 ? 1440 7195 71940
Here the given series follows a pattern of
4
4 x 10 - 10 = 30
30 x 5 - 5 = 145
145 x 10 - 10 = 1440
1440 x 5 - 5 = 7195
7195 x 10 - 10 = 71940
Hence, the missing number is 145
Given nuber series is 15, 30, ? , 40, 8, 48
Here the number series follows a pattern that
15
15 x 2 = 30
30 3 = 10
10 x 4 = 40
40 5 = 8
8 x 6 = 48
Hence, the missing number in the series is 10.
