paramanand  (11 years ago)

98-50=48
50-26=24
26-14=12
14-8=6
so in all above,the no subtracted is halved everytime..hence
6/2=3
subtract 3 in 8 ie 8-3=5
this is right answer

as
98-50=48
50-26=24
26-14=12
14-8=6
8-x=3
x=5;
98,50,26,14,8,5

ayushi garg  (11 years ago)

as 98-50=48
50-26=24
26-14=12
14-8=6
so to get 3 we have to subtract
8-5=3
hence ans is 5

Is this solution Helpfull? Yes | No   

QuickSilver  (11 years ago)

Answer is 3.

The difference between 2 consecutive no. is like

98-50 = 48 which can be written as 6*8 which can be written as 6*(2^3)
50-26 = 24 which can be written as 6*4 which can be written as 6*(2^2)
26-14 = 12 which can be written as 6*2 which can be written as 6*(2^1)
14-08 = 06 which can be written as 6*1 which can be written as 6*(2^0)

therefore the next no. will be written as 6*(2^(-1)) i.e 6*(1/2) which is equal to 3.

So the answer is 3

Is this solution Helpfull? Yes | No (1)  

Pravin Kahandki  (11 years ago)
