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.
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: 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: 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: 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: 181
Explanation:
Here the series follow the rule that
SO NEXT IS,
Correct Answer: 225
Explanation:
The series follows the following pattern
5 X 5 ? 5 = 20
20 X 4 ? 4 = 76
76 X 3 ? 3 = 225
225 X 2 ? 2 = 448
Hence, the term 225 denoted by (d) completes the series
Correct Answer: 63
Explanation:
Here the series follows the pattern that, product of succesive prime numbers i.e,
2 × 3 = 6
3 × 5 = 15
5 × 7 = 35
7 × 11 = 77
11 × 13 = 143
13 × 17 = 221
17 × 19 = 323
So here in place of 77 the number 63 is written.
So the wrong number is 63.
Correct Answer: 14
Explanation:
Here the given series is 128, 32, 14, 2.66, 0.88
128 / 4 = 32
32 / 3 = 10.666
10.666 / 4 = 2.666
2.666 / 3 = 0.888
Hence, the odd man in the given number series is 14.
Correct Answer: 44
Explanation:
4 3 4 7 15 ?
×1-1 ×1+1 ×2-1 ×2+1 ×3-1
15x3 - 1 = 45 - 1 = 44
