Logical Reasoning - Number Series - Discussion

The solution is;

14*2=28, 28-8=20;.
20*2=40, 40-8=32;.
32*2=64, 64-8=56;.

14, 28, 20, 40, 32, 64, (56)

14(+6)-->>20.
20(+12)-->>32.
32(+24)-->>56.

28(+12)-->>40.
40(+24)-->>64.
64(+48)-->>112.

14+6 = 20.
20+(6*2) = 32.
32+24 = 56.

One more answer is possible. 50
14 , 28(14x2) , 20(14+6), 40(20x2), 32(20+6x20) , 64(32x2), 50(32+6x3), 100(50x2)

The series is : 14 28 20 40 32 64

14+6=20
20+12=32
32+24=56

28+12=40
40+24=64

Each time the number doubles
i.e first we add 6
Then double of 6 i.e 12
After that we double 12 i.e 24..
In this way, we can get the answer.

14*2=28

28-8=20

20*2=40

40-8=32

32*2=64

64-8=56

14, 28, 20, 40, 32, 64, ...X?

32- 20 = 12
20 - 14 = 6

Hence X - 32 = 24 i.e {6,12,24...}
Then = 32+ 24= 56

X = Answer is 56

14,28,20,40,32,64,x
*2
-8
*2
-8
*2
-8

If we see odd place of this series then we find every digit is increase by adding table of 6 like
14+6=20
20+12=32 now the ans is
32+18=50

So the right answer is 50.

Good one Question......P, rajendran is also right.

It's a series of number in which number is alternativaly changed by as usually +X and -8 and where X is jsut got number when it has a turn of +X to change series and then we use -8 and again we use +X which is the just got number by using -8.

Now we again using -8 and got a nuber and now we use +X where X is the just got number [normal like we are changing by +3 and -1.......only instead od fix 3 we have changable X that is changed in every step].
