Correct Answer: 309
Explanation:
The pattern in the given series is +4, +9, +16, +25, ... i.e.
The next number is 284+25 = 309.

b c c b | b c c b | b c c b
Correct Answer: 45
Explanation:
First difference is 6 and second is 12. But if we take third as 18, then fourth difference will be 24. Then 93 can not be the last term.
So we have to take the difference as 6, 12, 24 and 48.
So Answer is 21+24 = 45
Correct Answer: 125
Explanation:
The pattern is *2,*5/2,*2,*5/2,*2, . . . . .
So missing term is 50*(5/2)=125
Correct Answer: 2.0
Explanation:
The pattern is +0.05,+0.1,+0.15, . . . .
so missing term =1.8+0.20=2.0
Correct Answer: 24.75
Explanation:
The given number series is 22, 11, 33, 16.5, 49.5, ?
22
22 / 2 = 11
11 x 3 = 33
33 / 2 = 16.5
16.5 x 3 = 49.5
49.5 / 2 = 24.75
Hence, the next number series is 24.75.
Correct Answer: 23
Explanation:
The given number series 11, 12.2, 14.6, 18.2, ?
11
11 + 1.2 = 12.2
12.2 + 2.4 = 14.6
14.6 + 3.6 = 18.2
18.2 + 4.8 = 23
Hence, the next number in the given number series is 23.
Correct Answer: 34
Explanation:
The given number series is 10, 6, 8, 15, ?
10
10 x 0.5 + 1 = 6
6 x 1 + 2 = 8
8 x 1.5 + 3 = 15
15 x 2 + 4 = 34
Hence, the next number in the given series is 34.
Correct Answer: 85
Explanation:
The correct pattern is +9,-7,+5,-3,+1
So,85 is wrong term and must be replaced by 90-3=87
