Q. What is the next number of the following sequences
1. 4,2,36,4,5,1,36,16,6,3,81,?
2. 7,6,5,4,6,5,9,?
3. 3,12,29,?
4. 3,8,12,48,29

• 1. 4,2,36,4....5,1,36,16.....6,3,81,___
  4+2=6,3rd term is 6^2,
  4-2=2 4th term is 2^2
  Similarly
  6+3=9,3rd term is 9^2 = 81
  6-3=3,4th term is 3^2 = 9
  
  2. 7,6...5,4.....6,5.....9,__
  7 - 6 = 1
  5 - 4 = 1
  similarly
  9 - x = 1
  x = 8
  
  3. 3,12,29,__
  3 * 2 + 6 = 12
  12 * 2 + 5 = 29
  similarly
  29 * 2 + 4 = 62

• 3) 3,12,29,...
  1^2+2=3,
  3^2+3=12
  5^2+4=29
  7^2+5=54
  so series is 3,12,29,54

• consider set of 4 {4,2,36,4}
  4+2=6,third term is 6^2,4-2=2 fourth term is 2^2
  as follows ans is 9

• 3,8,12,48,29 take alternate terms..
  (1^2+2),((1+2)^2+3),((3+2)^2+4) similarly the next term would be ((5+2)^2+5)=54
  (3^2-1),((3+4)^2-1) similarly next term would be ((7+4)^2-1)=120
  so the series is 3,8,12,48,29,120,54
• 10 years agoHelpfull: Yes(5) No(2)
• 4. 1^2+2=3
  2^2*2=8
  3^2+3=12
  4^2*3=48
  5^2+4=29
  6^2*4=144

• 4.(3,8),(12,48),(29,..)
  8=3*3-1
  48=7*7-1
  ans=11*11-1
  =120

• 1.
  4+2=6^2=36;4-2=2^2=4
  5+1=6^2=36;5-1=4^2=16
  6+3=9^2=81;6-3=3^2=9
  so ans is 9
• 10 years agoHelpfull: Yes(3) No(0)
• 2)7,6,5,4,6,5,9,?
  7-6=1
  5-4=1
  6-5=1
  similarly 9-x=1 so x=8

• 1.36 is after a gap of 2,3,then 4.
  so after 81 it will be 36

• 3)3,12,29,?
  ans:
  (1^3)+2=3
  (2^3)+4=12
  (3^3)+2=29
  so ans is (4^3)+4=68
  
  depending on the choice choose the ans ........
  (both 54 and 68 suits well)

• 10 years agoHelpfull: Yes(0) No(1)
• 1. 4,2,36,4,5,1,36,16,6,3,81
  (4+2=6 6*6=36)
  (5+1=6 6*6=36)
  (6+3=9 9*9=81)
  then left term 4 is 4*4=16
  in the last term 16*16=256
  so ans is 256

• 3.
  1^3+2=3,
  2^3+4=12,
  3^3+2=29,
  4^3+4=68(ans)...

• 4).
  3,8,12,48,29
  
  1^2+2=3
  2^2*2=8
  3^2+3=12
  4^2*3=48
  5^2+4=29
  6^2*4=144

• 7,6,5,4,6,5,9,?
  so we can split it in two parts (7,6,5,4),(6,5,9,?)
  now 6+5-7=4
  same way 9+5-6=8
  so the ans is 8

• i think 3rd question is little bit confusing because it has number of solutions
  3,12,29,?
  3*3^1 = 9+3 = 12
  3*3^2 = 27+2 = 29
  3*3^3 = 81+1 =82.............this is also satisfying

• given series is
  3,8,12,48,29,?
  logic is 1^2+2=3,2^2*2=8,3^2+3=12,4^2*3=48,5^2+4=29,6^2*4=144 ANS

• compare with the set of numbers in the question with below pattern
  x, y, (x+y)^2 , (x-y)^2
  
  So, the first set of numbers we get are
  4, 2, (4+2)^2 = 36, (4-2)^2 = 4 .... do the same with rest of the numbers and you will get
  1) 4, 2, 36, 4
  2) 5, 1, 36, 16
  3) 6, 3, 81, ( 9 ) Answer
