Correct Answer: 1/27
Explanation:
Clearly, the numerators of the fractions in the given sequence follow the series of 2, 3, 5, 7,... and the denominator follows 3, 9, 27, 81, 243, ...
Then, the next term in the given sequence is
.
Correct Answer: 445
Explanation:
The given series is 1, 2, 6, 21, 88, ?
1
1 x 1 + 1 = 2
2 x 2 + 2 = 6
6 x 3 + 3 = 21
21 x 4 + 4 = 88
88 x 5 + 5 = 445
Hence, the next number in the given number sequence is 445.
Correct Answer: 336
Explanation:
3 x 3 x 3 = 27 - 3 = 24
4 x 4 x 4 = 64 - 4 = 60
5 x 5 x 5 = 125 - 5 = 120
6 x 6 x 6 = 216 - 6 = 210
7 x 7 x 7 = 343 - 7 = 336

Correct Answer: 15
Explanation:
Two series alternate here, with every third number following a different pattern.
In the main series, 4 is added to each number to arrive the next.
In alternate series, 5 is subtracted from each number t arrive the next number.
Here in the main series
3 + 4 = 7
7 + 4 = 11
11 + 4 = 15
15 + 4 = 19
In alternate series
24 - 5 = 19
19 - 5 = 14...
Correct Answer: 629
Explanation:
The pattern is *3,+2,*5,+4,*7,+6, . . . . .
So missing term is 623+6=629
Correct Answer: 183
Explanation:
The given number series is 1 8 36 ? 1100 7701
It follows a pattern that,
1
1 x 3 + 5 = 8
8 x 4 + 4 = 36
36 x 5 + 3 = 183
183 x 6 + 2 = 1100
1100 x 7 + 1 = 7701
Hence, the missing number in the given series is 183.
Correct Answer: 129
