  break the series into groups taking 3elements in a group.now see the difference between the first two is the third....like....
  5/6-1/3=1/2
  1/2-2/8=1/4.....like this

• 5.) 2,6,5,14,11,26,17,?
  split it into two series.
  2,5,11,17 are alternating prime numbers.
  6*2=12+2=14
  14*2=28-2=26
  so 26*2=52+2=54
  so answer s 54
• 10 years agoHelpfull: Yes(2) No(2)
• 9.) 2,7,-35,7,12,-60,5,10,?
  series goes lyk +5, *(-5), /(-5)
  2+5=7
  7*(-5)= -35
  -35/(-5)= 7
  7+5=12
  12*(-5)= -60
  -60/(-5)= 5
  5+5=10
  10*(-5)= -50
  so answer s -50

• 3. 5/6,1/3,1/2,1/2,2/8,1/4,5/6,1/6,2/3,1/2,1/3,?
  multiple of 24 so(Ex 5/6*24=20,1/3*24=8........ 1/3*24=8)
  20,8,12,12,6,6,20,4,16,12,8,?
  20-8=12
  12-6 = 6
  20-4 = 16
  12-8 = 4
  so ans is 4.
  4. 3/2,9/4,9/4,7/2,49/2,49/4,4/3,16/9,16/9,8/3,?

  4/3*4/3=16/9
  8/3*8/3=64/9
  so ans is 64/9
  6. 6,18,21,8,11,33,2,6,9,5,8,24,7,21,?
  18/6=3 18+3=21 or 11-3=8
  33/11=3
  6/2 = 3 6+3 = 9 or 8-5 =3
  24/8 = 3
  21/7 = 3 21+3 =24
  so ans is 24
  9. 2,7,-35,7,12,-60,5,10,?
  -35/7 = 5
  -60/12 = 5
  X/5 = 5
  put the value of X is -50

• split the series in to two
  5. 2,5,11,17 and other one is 6,14,26
  in the second series 2 is multiplied by a prime number
  2*3=6, leave 5 then 2*7=14, leave 11 then 2*13=26...so leave 17 and 2*19=38 will be the answer
