Correct Answer: 650
Explanation:
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.
Correct Answer: 13
Explanation:
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.
Correct Answer: 437

Correct Answer: 35
Explanation:
48, 54, 63, 81 and 105 are divisible by 3 but not 35.
Correct Answer: 34
Explanation:
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.
Correct Answer: 10
Explanation:
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.
Correct Answer: 29
Explanation:
Here the given number series follows a pattern of two alternate series.
1. 7 19 31 ...(Difference of 12)
2. 9 18 27 ...(Difference of 9)
Here the odd number is 29 instead of 27
And the next number is 31 + 12 = 43 & 27 + 9 = 36
Correct Answer: 82.5
Explanation:
The given series
12 24 26.5 79.5 ? 330 follows a pattern that,
12 x 2 = 24
24 + 2.5 = 26.5
26.5 x 3 = 79.5
79.5 + 3 = 82.5
82.5 x 4 = 330
Hence, the missing number is 82.5
Correct Answer: 21 months
Explanation:
Total savings = 200 + 200 + 200 + 240 + 280 + ... to n months = 11040
= 120 + 80 + 160 + 40 + 200 + 240 + ....n terms
= 40 + 80 + 120 + 160 + 200 + 240 + ...n terms
= n/2[2a + (n-1)d] + 80 + 40 = 11040
= n/2[240 + (n-1)40] = 10920
= n[6+n-1] = 546
= n[n+5] = 546
n = 21
