4> Format=> (1st+2nd)/3rd=4th
so, (0+1)/2=0.5
(2+2)/2=2
(4+3)/2=3.5
so next number will be 3.5

Is this solution Helpfull? Yes (11) | No (1)  

anuj agrawal  (7 years ago)

Q5. Take set of 3 numbers in the given series and apply +6 on first then -12 on second number consecutively.
-5 + 6 = 1
1 - 12 = -11
---------------------------------
23 + 6 = 29
29 - 12= 17
---------------------------------------
-20 +6= -14
-14 - 12= -26
So answer will be: -26

Vivek Gupta  (7 years ago)

13-->0.03,0.0018,0.00108,0.00648,0.3888
Series Goes as
0.03*0.06 = 0.0018
0.0018*0.6=0.00108
0.00108*6=0.00648
0.00648*60=0.3888
so next will be
0.3888*600=233.28

Answer Will be 233.28

12-->2,1/3,2/3,6,7,1/2,7/2,14,20,1/5,4
Divide in Group of 4
(2,1/3,2/3,6)
2*1/3 == 2/3
2divided by1/3 ==6

Simillary in last group
(20,1/5,4)
20*1/5 == 4
20 divided by 1/5 == 100

Answer will be 100

Rahul KUmar  (7 years ago)

Q1. 7,-35,-34, -3,15,16, 4,?
(7) * -5 = (-35), (-35) + 1 = (-34) Here () means given number in series
(-3) * -5 = (15), (15) + 1 = (16)
(4) * -5 = (-20) So I think answer is -20

Anshuman Pandey  (7 years ago)

12> 2,1/3,2/3,6,7,1/2,7/2,14,20,1/5,4
as 2*1/3=2/3
7*1/2=7/2
20*1/5=4
we will take square of denominator and multiply
now 2/3*(3^2)=6
again 7/2*(2^2)=14
so the term would be 4/1*(1^2)=4

Ram Prasad  (7 years ago)

0,1,2,0.5,2,2,2,2,4,3,2,?

Ans--> Step1: take first 4 digits (0,1,2,0.5)
0+1=>1/2=>0.5
Step2: take next 4 digits (2,2,2,2)
2+2=> 4/2=>2
Step3: take next 4 digits(4,3,2,x)
4+3=> 7/2 => 3.5
Therefore x=3.5

prabhakar reddy D  (7 years ago)

10-->2/3,5/3,19/6,31/6,23/3,32/3,84/6,(i think here 85/6)

make denominators equal
4/6,10/6,19/6,31/6,46/6,64/6,85/6,......
now the numerators are in series
4,10,19,31,46,64,85,..
observe gap between numbers
+6,+9,+12,+15,+18,+21
so 85+24=109

ans: 109/6
