33,8,41,46,21,67,72,47,119,124,?

• 33+8 = 41 33-8 = 25
  46 + 21 = 67 46 - 21 =25
  72 + 47 = 119 72-47 = 25
  124 + 99 124 - 99 = 25 answer = 99

• 33+8=41
  46+21=67
  72+47=119
  124+?
  Now see the difference b/w 33 and 46 is 13 same in 8 and 21
  after that 26 is the difference 46 and 72 and so on...
  then 52 is the differnce
  it means diff is doubled every time
  hence 47+52=99 Ans

• 33-25=8 & 41+5=46
  46-25=21 & 67+5=72
  72-25=47 & 119+5=124
  124-25=99

  46-21=25
  72-47 = 25
  so 124-? should also be 25. 124-?=25
  ? =124-25=99

• ans 25
  33+8=41,46+21=67,...
  33-25 = 8,46-25=21..
  so 124-25 = 99

• 33+8=41
  46+21=67
  72+47=119
  there fore it is a 3 series qn
  46-33=13
  21-8=13
  67-41=26(13*2)
  72-46=26
  47-21=26
  119-67=52(multiple of 13i.e. 13*4)
  therefore 124-72=52
  so next number difference is also 52
  47-x=39
  --> x=86

• 8,21,47 are in series ie= 8+13=21+13*2=47+13*3=85 is the ans
  41+5=46,67+5=72,119+5=124 this is the ans and logic !!

• @ Shreya,
  
  What is the fun in copy pasting question and answer ?

• make it in pairs of three
  
  let (a,b,c) be nth term then
  a = 33 + [ 13n(n-1) / 2 ]
  b = 8 + [ 13n(n-1)/2 ]
  c = a + b = 41 + 13n(n-1)

• 33-4=25, 8-41=-33
  46-21=25,21-67=-46=33*13
  72-47=25,47-119=72=33*13*2
  124-x=25=>x=99 ans=99

• sorry that was my mistake that was + not *
  33-8=25, 8-41=-33
  46-21=25,21-67=(-33-13)
  72-47=25,47-119=(-33-13)*2
  124-x=25=>x=99 ans=99

• 33+8 = 41 33-8 = 25
  46 + 21 = 67 46 - 21 =25
  72 + 47 = 119 72-47 = 25
  124 + 99 124 - 99 = 25 answer = 99
