191. One term in the number series is wrong. Find out the wrong term.
8, 14, 26, 48, 98, 194, 386
So, 48 is wrong and must be replaced by (26 x 2 - 2) i.e. 50.
8, 14, 26, 48, 98, 194, 386
Solution:
The correct pattern is x 2 - 2.So, 48 is wrong and must be replaced by (26 x 2 - 2) i.e. 50.
192. One term in the number series is wrong. Find out the wrong term.
3, 10, 27, 4, 16, 64, 5, 25, 125
So, 10 is wrong and must be replaced by 32 i.e. 9.
3, 10, 27, 4, 16, 64, 5, 25, 125
Solution:
The correct sequence is 3, 32, 33, 4, 42, 43, 5, 52, 53.So, 10 is wrong and must be replaced by 32 i.e. 9.
193. One term in the number series is wrong. Find out the wrong term.
1, 5, 9, 15, 25, 37, 49
So, 15 is wrong and must be replaced by (42 + 1) i.e. 17.
1, 5, 9, 15, 25, 37, 49
Solution:
The terms of the given series are 12, (22 + 1), 32, (42..+ 1), 52, (62 + 1), 72.So, 15 is wrong and must be replaced by (42 + 1) i.e. 17.
194. One term in the number series is wrong. Find out the wrong term.
4, 10, 22, 46, 96, 190, 382
So, 96 is wrong and must be replaced by (46 + 48) i.e. 94.
4, 10, 22, 46, 96, 190, 382
Solution:
The correct pattern is + 6, + 12, + 24, + 48, + 96, + 192.So, 96 is wrong and must be replaced by (46 + 48) i.e. 94.
195. One term in the number series is wrong. Find out the wrong term.
2, 6, 24, 96, 285, 568, 567
So, 24 is wrong and must be replaced by (6 x 5 - 5) i.e. 25.
2, 6, 24, 96, 285, 568, 567
Solution:
The correct pattern is x 6 - 6, x 5 - 5, x 4 - 4,.....So, 24 is wrong and must be replaced by (6 x 5 - 5) i.e. 25.
196. One term in the number series is wrong. Find out the wrong term.
3, 2, 8, 9, 13, 22, 18, 32, 23, 42
I. 3, 8, 13, 18, 23 and II. 2, 9, 22, 32, 42
The pattern in I is + 5, and the pattern in II is + 10. So, in II, 9 is wrong and must be replaced by (2 + 10) i.e. 12.
3, 2, 8, 9, 13, 22, 18, 32, 23, 42
Solution:
The given sequence is a combination of two series:I. 3, 8, 13, 18, 23 and II. 2, 9, 22, 32, 42
The pattern in I is + 5, and the pattern in II is + 10. So, in II, 9 is wrong and must be replaced by (2 + 10) i.e. 12.
197. One term in the number series is wrong. Find out the wrong term.
196, 169, 144, 121, 101
So, 101 is wrong and must be replaced by (10)2 i.e. 100.
196, 169, 144, 121, 101
Solution:
The sequence is (14)2, (13)2, (12)2, (11)2, (10)2.So, 101 is wrong and must be replaced by (10)2 i.e. 100.
198. One term in the number series is wrong. Find out the wrong term.
56, 58, 62, 70, 84, 118, 182
So, 84 is wrong and must be replaced by (70 + 16) i.e. 86.
56, 58, 62, 70, 84, 118, 182
Solution:
The correct pattern is + 2, + 4, + 8, + 16, + 32, + 64 i.e. + 2, + 22, + 23, + 24, + 25, + 26.So, 84 is wrong and must be replaced by (70 + 16) i.e. 86.
199. One term in the number series is wrong. Find out the wrong term.
1, 5, 5, 9, 7, 11, 11, 15, 12, 17
I. 1, 5, 7, 11, 12 and II. 5, 9, 11, 15, 17
The pattern in both I and II is + 4, + 2, + 4, + 2. So, 12 is wrong and must be replaced by (11 + 2) i.e. 13.
1, 5, 5, 9, 7, 11, 11, 15, 12, 17
Solution:
The given sequence is a combination of two series:I. 1, 5, 7, 11, 12 and II. 5, 9, 11, 15, 17
The pattern in both I and II is + 4, + 2, + 4, + 2. So, 12 is wrong and must be replaced by (11 + 2) i.e. 13.
200. One term in the number series is wrong. Find out the wrong term.
25, 36, 49, 81, 121, 169, 225
25, 36, 49, 81, 121, 169, 225
Solution:
The correct sequence is 52, 72, 92, 112, 132, 152. So, 36 is wrong.
