• 1) denominator is 3,2,4,3,2,4,............
  at numerator 6 is added after 3 terms
  so next terms are: 13/4, 19/3, 19/2, 19/4, ..............

• 3)5,50,10,40,15,30,20,20,_?
  Ans: Take the series as Even and Odd
  For every even number 10 will be reduced 50,,40,30,20
  for every odd number 5 willl be increased 5,10,15,20
  so the answer is 25

  5*2=10+7=17
  17*2=34+3=37
  37*2=74-7=67
  67*2=174-3=131
  multiply with 2 then alternatively add n sub +7,+3,-7,-3

• 6) add the first two terms to get the third term- 7/6+2/3=11/6... 13/6+5/2=28/6..ans=28/6

• 4) It is a combo of two series
  1-> 5,10,15,20 next 25
  2-> 50,40,30,20 next 10
  
  so next two terms are 25,10

  next term is 2
• 9 years agoHelpfull: Yes(2) No(0)
• 9)ans:17
  by seeing alternative numbers we have first difference is 1 and after that for the next series add 5 and after that also add 5.

  1/3 +2=7/3

  2.{18,6},[24,4],{30,10},[12,2],{6,_}
  
  every pair in {} is divided by 3
  and every pair in [] is divided by 4
  and this continues alternatively
  
  18/3 = 6 ... 24/6 = 4
  30/3 = 10 .. 12/6 = 2
  6/3 = 2
  Ans : 2
  
  3.
  2 Series:
  1st Series: 9, 26/3, 25/3, 8, ? 2nd Series: 15, 29/2, 14, 27/2
  
  1st Series can be rewritten as -> 27/3, 26/3, 25/3, 24/3, ? => here it decreases by 1/3
  and 2nd series can be written as -> 30/2 , 29/2 , 28/2 , 27/2 ..... => here it decreases by 1/2
  
  So Next number will be: 24-1/3 - 1/3 = 23/3 Ans
  
  4.Ans: 25
  5,10,15,20; (+5)Series. Next one will be 25
  50,40,30,20; (-10)Series. Next on will be 10
  
  5.this question is wrong, the correct series will be
  1.25,3,7.1,1.50,1,8.1,1.75,-1,?
  
  ans=9.1
  in that series +.5,-2,+1 added as so that no. would be 3rd no.right to that no.
  1.25+.5=1.50
  3-2=1
  7.1+1=8.1
  1.50+.25=1.75
  1-2=-1
  8.1+1=9.1

  11.5 =11.5
  11.5 +(6) = 17.5
  17.5 +(6*3) = 17.5 + 18 = 35.5
  35.5 +(18*3) = 35.5 + 54 = 89.5
