Correct Answer: 980
Explanation:
The given series follows the pattern that,
×5+5, ×5+5, ×5+5, ×5+5, ×5+5
38 x 5 + 5 = 195
195 x 5 + 5 = 980
980 x 5 + 5 = 4905
4905 x 5 + 5 = 24530
24530 x 5 + 5 = 122655
So the missing number is 980 .
Correct Answer: 36
Explanation:
The given number series is 90 72 56 42 36 20
9 x 10 = 90
8 x 9 = 72
7 x 8 = 56
6 x 7 = 42
5 x 6 = 30 (not 36)
4 x 5 = 20
Hence, the odd man in the given number series is 36.
Correct Answer: 450.187
Explanation:
Pattern is
Correct Answer: 47
Explanation:
The next number in the series is
143 143 136 110
0 7 26 (Differences)
Correct Answer: 156
Explanation:
Here the given series 7 18 42 94 204 follows a pattern that,
7
7 ×2+4 = 18
18 ×2+6 = 42
42 ×2+10 = 94
94 ×2+16 = 204
Similarly,
4
4 ×2+4 = 12
12 ×2+6 = 30
30 ×2+10 = 70
70 ×2+16 = 156
Hence, the value of P = 156.
Correct Answer: 98
Explanation:
The given number series is
3, 5, 8, 15, 28, 51, ?
Here the pattern it follows is
3
3 + 2 = 5 ( add prime number less than 3 i.e, 2)
5 + 3 = 8 (3 is prime number less than 5)
8 + 7 = 15 (7 is prime number less than 8)
15 + 13 = 28 (13 is prime number less than 15)
28 + 23 = 51 (23 is prime number less than 28)
51 + 47 = 98 (47 is prime number less than 51)
Hence, the next number in the given number series is 98.
Correct Answer: 635
Explanation:
Given Number series is 18 37 76 155 314 635
follows a pattern that,
18
18 x 2 +1 = 37
37 x 2 +2 = 76
76 x 2 +3 = 155
155 x 2 +4 = 314
314 x 2 +5 = 633 not 635
Hence, the odd man is 635.
Correct Answer: 132
Explanation:
Given series is
12 16 32 68 ?
Here it follows a pattern that,
12
12 + (2x2) = 16
16 + (4x4) = 32
32 + (6x6) = 68
68 + (8x8) = 132
Correct Answer: 28
Explanation:
Here the given series 1, 6, ?, 15, 45, 66, 91 follows a
Pattern in the series is, +5, +9, +13,...,.. +21, +25
So +4 is getting increased at every term addition.
Missing Number in the series will be 15+(9+4) = 15 + 13 = 28.
Correct Answer: 284
Explanation:
114 131 165 216 ? 369
+17 +34 +51 +68 +85
=> The missing number in the given Number series = 216 + 68 = 284.
