In this type of questions, one term in the number series is wrong. Find out the wrong term.
24576, 6144, 1536, 386, 96, 24
Answer: Option B
Explanation:
Each term of the series is obtained by dividing the preceding term by 4.
So, 1536 is wrong and must be replaced by (1536 + 4) i.e. 384.
10, 14, 28, 32, 64, 68, 132
Answer: Option D
The correct pattern is + 4, x 2, + 4, x 2, .....
So, 132 is wrong and must be replaced by (68 x 2) i.e. 136.
46080, 3840, 384, 48, 24, 2, 1
Answer: Option C
The correct pattern is ÷ 12, ÷ 10, ÷ 8,÷ 6,.....
So, 24 is wrong and must be replaced by (48 + 6) i.e. 8.
89, 78, 86, 80, 85, 82, 83
The correct pattern is - 11, + 9, - 7, + 5, - 3, + 1.
So, 86 is wrong and must be replaced by (78 + 9) i.e. 87.
0, 2, 3, 5, 8, 10, 15, 18, 24, 26, 35
Answer: Option A
The given sequence is a combination of two series:
I. 0, 3, 8, 15, 24, 35 and II. 2, 5, 10, 18, 26
The pattern in both I and II is + 3, + 5, + 7, + 9,.....
So, in II, 18 is wrong and must be replaced by (10 + 7) i.e. 17.
