• g)2,6,5,14,11,26,17,?
  
  
  ans is 38
  
  here we are multiply with 2 the alternate prime numbers
  
  2 , (3*2)=6 , 5 , (7*2)=14 , 11 , (13*2)=26 , 17 , (19*2)=38
• 8 years agoHelpfull: Yes(14) No(0)
• n) 1) 18+3=21-4=17+7=24; (18, 21, 17, 24)
  2) 24+3=27-4=23+7=30 (24, 27,23, 30)
  3) 5+3=8-4=4+7=11 (5, 8, 4, 11)
  So the missing number is 11.

• b) answer is 3.5
  decide the numbers in series ,
  0. 1. 1. 2. 0.5
  2. 2. 4. 2. 2
  4. 3. 7. 2. ?
  in this take first row 0 (0+2=2)
  2(2+2=4)
  4
  again consider 2 and row 1,2,3( difference b/w each no is 1)..so repeat the same process for all the rows ,last row (0.5,2,?)
  ans:-0.5+1.5=2
  2+1.5=3.5

  1*1=1 ---> add 1 to result 1+1=2
  
  2*2=4 ---> add 2 to result 4+2=6
  
  6*6=36 ---> add 3 to result 36+3=39
  
  39*39=1521 --> add 4 to result 1521+4=1525
  
  e) 2,9,5,49,11,169,?
  
  ans is 17
  
  here we are square the alternate prime numbers
  
  2 3*3=9 5 7*7=49 11 13*13=169 17
  
  f) 49,7,98,16,4,48,9,3,36,25,5,?
  
  ans is 125
  
  divide into groups (49,7,98),(16,4,48),(9,3,36),(25,5,?)
  
  in first group to get 2nd num divide 49/7=7
  
  to get 3rd num divide 49*2=98
  
  in second group to get 2nd num divide 16/4=4
  
  to get 3rd num divide 16*3=48
  
  in third group to get 2nd num divide 9/3=3
  
  to get 3rd num divide 9*4=36
  
  in fourth group to get 2nd num divide 25/5=5
  
  to get 3rd num divide 25*5=125
  
  g) 2,6,5,14,11,26,17,?
  
  ans is 39
  
  divide 2 num as pair (2,6),(5,14),(11,26),(17,?)
  
  6-2= 4 add 5 to get next pair diff 4+5=9
  
  14-5=9 add 6 to get next pair diff 9+6=15
  
  26-11=15 add 7 to get next pair diff 15+7=22
  
  here we don't know x, but we know result of next pair
  
  x-17=22 on solving this equation we get x=39
  
  l) 13,24,36,23,34,56,33,44,96,43,54,?
  
  divide numbers as (13,24),36,(23,34),56,(33,44),96,(43,54),(?)
  
  24-13=11 36 34-23=11 56 44-33=11 96 54-43=11 ?
  
  11 36 11 56 11 96 11 ?
  
  from the above series diff b/w alternate numbers are
  
  56-36=20
  
  96-56=40=20*2
  
  x-96=80=40*2 ---> on solving we get x=176

  --------------------------------------------------------------------------------
  ANS-96
  solution a) divide series into 4 parts-
  (13,24,36)(23,34,56)(33,44,76)(43,54,?)
  13+24=37-1=36
  23+34=57-1=56

  solution b)Divide series into 4 parts like above -
  13+11=24,24+12=36
