Logical Reasoning Questions and Answers
Which of the following will come in place of the question mark (?) in the following sequence?
PRODUCTIVITY, RODUCTIVIT, ODUCTIVI, ?
PRODUCTIVITY = RODUCTIVIT.(Bold letters are removed.)
RODUCTIVIT = ODUCTIVI.
ODUCTIVI = DUCTIV.
Complete the series 6, 24, 60,120, 210, ?
First Number = 1 *2 *3 = 6
Second Number = 2*3*4 = 24
Third Number = 3*4*5 = 60
Fourth Number = 4*5*6 = 120
Fifth Number = 5*6*7 = 210
Sixth Number = 6*7*8 = 336.
Alternatively,
2*2*2-2=6
3*3*3-3=24
4*4*4-4=60
5*5*5-5=120
6*6*6-6=210
7*7*7-7=336.
Complete the series 6, 11, 31, 121, 601, ?
First Term = 6.
Second term = 6*2 -1 = 11.
Third term = 11* 3 - 2 = 31.
Fourth term = 31 *4 - 3 = 124 -3 = 121.
Fifth term = 121*5 - 4 = 601.
Sixth term = 601 *6 = 3606 - 5 = 3601.
Complete the series 7, 11, 19, 35, 67, ?
Last Term *2 - 3 = Next Term.
First Term = 7.
Second Term = 7 *2 -3 = 11.
Third Term = 11 *2 - 3 = 19.
Fourth Term = 19 *2 - 3 = 35.
Fifth Term = 35 *2 - 3 = 67.
Sixth Term = 67 *2 -3 = 131.
Complete the series 8, 22, 64, 190, 568, ?
Logic:
Previous Term *3 - 2 = Next term.
First Term = 8.
Second term = 8 *3 - 2 = 24 -2 = 22.
Third term = 22 *3 -2 = 64.
Fourth term = 64 *3 -2 = 190.
Fifth Term = 190 *3 - 2 = 568.
Sixth Term = 568 *3 -2 = 1704 -2 = 1702.
Complete the series 5760, 2880, 960, 240, 48, ?
First Term = 5760.
Second term = 5760 /2 = 2880.
Third Term = 2880/3 = 960.
Fourth term = 960/4 = 240.
Fifth term = 240/5 = 48.
So,
Required term = 48/6 = 8.
