Q. What is the next number of the following sequence

1)11.5,17.5,35.5,89.5,?

2)12,3,15,14,6,19,9,23,18,12,?

3)10,12,-36,-7,-5,15,19,21,?

4)7,0,1,8,5,12,9,26,3,23,2,?

5)3,12,29,?

6)3,8,12,48,29,?

7)1.25,3.71,1.50,1,8.1,1.75,-1,9.1,2.00,?

9)5,16,22,68,28,87,36,106,11?

• 1.difference btw 1st and 2nd term is 6,2nd and 3rd term is 18,3rd and 4th term is 54 i.e.6,18,54 so next difference will be 162 so next term is 251.5

• 4)28
  (7+0+1=8),(5+12+9=26),(3+23+2=28)
  
  5)62
  3*2+6=12
  12*2+5=29
  29*2+4=62

• 9)5,16,22,68,28,87,36,106,11?
  5*3=15+1=16
  22*3=66+2=68
  28*3=84+3=87
  36*3=108+4=112(its nt 106 i think)
  11*3=33+5=38...is the ans.
• 10 years agoHelpfull: Yes(8) No(0)
• 3) ans is 21*-3=-63 ,,12*-3=-36,-5*-3=15
  4)3+23+2=28
  
  
• 10 years agoHelpfull: Yes(7) No(0)
• 2) 21
  alternately there is addition of 3
• 10 years agoHelpfull: Yes(7) No(12)
• 2) 12,3,15,14,6,19,9,23,18,12
  (12,3,15,14) (6,19,9,23)(18,12,x
  difference between 12 and 15 is -3
  in the 2nd part difernce between 6 and 9 is -3
  in the same way the difference between 18 and x must be -3
  so, the answer is 15

• 6)3,8,12,48,29,?
  (3,8),(12,48),(29,?)
  3*3-1=8
  12*4+0=48
  29*5+1=146 is the ans.

• Ans Q)5)
  1*1=1+2
  3*3=9+3=12
  5*5=25+4=29
  7*7=49+5=54(ans)
• 7 years agoHelpfull: Yes(3) No(0)
• 7) 1.25,3,7.1,1.50,1,8.1,1.75,-1,9.1,2.0 ?
  1.25+0.25=1.50
  3-2=-1
  7.1+1=8.1
  i.e. -3 ans
• 10 years agoHelpfull: Yes(1) No(1)
• 5) 3 12 29
  12-3=9
  29-12=7
  Hence,34 will b d answer(34-29=5)
• 8 years agoHelpfull: Yes(1) No(6)
• 17.5-11.5=6
  35.5-17.5=6*3
  89.5-35.5=18*3
  281.5-89.5=64*3

• 7)-3.71
  from the second term gettind reduced by -2.71,-2,-2.71 altrnately
• 10 years agoHelpfull: Yes(0) No(5)
• Take 3 at once,for each series adding 2 to the first term nd multiply it with -3
• 10 years agoHelpfull: Yes(0) No(0)
• 30. ans will be : -63
• 10 years agoHelpfull: Yes(0) No(0)
• srry....that will be(3). -63 ans

• 21, i guess. is it right?
• 9 years agoHelpfull: Yes(0) No(0)
• 1) 11.5,17.5,35.5,89.5,251.5... (11.5),(11.5 + 6),(17.5 + (6*3)),(35.5 + (6*3*3)),(89.5 + (6*3*3*3))....
  
• 9 years agoHelpfull: Yes(0) No(0)
• 5) the question is wrong
  
  the 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
• 7 years agoHelpfull: Yes(0) No(0)
• 3)10,12,-36,-7,-5,15,19,21?
  diff between 1th and 2nd number = -2 (10-12)
  diff between 4th and 5th number = -2
  diff between 7th and 8th number = -2...
  
  diff between 3th and 6th number = (-36-15)= -51
  next number is 15-66 = -51
  
  ans is 66.
