Logical Reasoning Questions and Answers

First term → 6
Second term → (6*2+1) = 13
Third term → (13*2+2) = 28
Fourth term → (28*2+3) = 59
Fifth term → (59*2+4) = 122
Sixth term → (122*2+5) = 249
So, the required term = 122.

Above series contains two sub-series in it.

4, 10, 16, 22

8, 14, 20

Each of both term there is difference of 6 i.e. next term is 6 greater than previous term.

First term → 9

Second term → (9 *2 -1) = 17

Third term → (17 *2 -1) = 33

Fourth term → (33 *2 -1) = 65

Fifth term → (65 *2 -1) = 129

First term → 2

Second term → (2 *3 -3) = 3

Third term → (3 *3 -3) = 6

Fourth term → (6 *3 - 3) = 15

sixth term → (15 *3 - 3) = 42

The given pattern is,
2^nd term → 1*2+1 = 3
3^rd term → 3*3+1 = 10
4^th term → 10*2+1 = 21
5^th term → 21*3+1 = 64
6^th term → 64*2+1 = 129
7^th term → 129*3+1= 388
So, 7^th term 356 is wrong and must be replaced by 388.

Given pattern is,
2^nd term → 9*3 = 27
3^rd term → 27+4 = 31
4^th term → 31*5 = 155
5^th term → 155+6 = 161.
6^th term → 161*7 = 1127
Missing term → 1127+8 = 1135.

The pattern is,
2^nd term → 2 +(5 *1²) = 7
3^rd term → 7 +(5 *2²) = 27
4^th term → 27 +(5 *4²) = 107
5^th term → 107 +(5 *8²) = 427
Missing term → 427 +(5 *16²) = 1707

Sunday to Monday = no gap
Monday to Wednesday = One day gap.
Wednesday to Saturday = Two days gap.
Saturday to Wednesday = Three days gap.
Wednesday to Monday = Four days gap.
In the next term there must be five days and six days gap.
So, Next term would be Sunday, Sunday.

Logic: Next term = Previous term /4
2816 /4 = 704
704 /4 = 176.
176 /4 = 44.
44 /4 = 11.

113
113 * 2 = 226 -1 = 225
225 * 2 = 450 -1 = 449
449 * 2 = 898 - 1 = 897
897 * 2 = 1794 -1 = 1793
