11. In the series 0, 3, 8, 15,__ What is the next number?

• 24
  
  series is n^2-1.
  1-1=0
  4-1=3
  9-1=8
  16-1=15
  25-1=24

• 3-0=3
  8-3=5
  15-8=7
  difference increasing by 2 every time
  next difference 9
  15+9=24

• 0, 3, 8, 15,24,35,....
  
  as numbers are one less than perfect squares.

• 0+3=3
  3+5=8
  8+7=15
  15+9=24
  ans=24
  note-> 3,5,7,9 are seqential odd numbers.

• 0+2=2+1=3
  3+4=7+1=8
  8+6=14+1=15
  15+8=23+1=24
  
  or
  
  0+2*1=2+1=3
  3+2*2=7+1=8
  8+2*3=14+1=15
  15+2*4=23+1=24
• 13 years agoHelpfull: Yes(2) No(1)
• Ans : 24
  Formula : n(n+2)
  Soln : 0(0+2) = 0
  1(1+2) = 3
  2(2+2) = 8
  3(3+2) = 15
  4(4+2) = 24

• Difference b/w the no. is equal to
  0-3=3
  3-8=5
  8-15=7
  so the difference b/w the difference is increasing by +2
  that is 3 5 7 so the next no has to be 9
  therefore, 15+9=24
  required no of the series is 24

• Ans is 24 series is n^2-1.

• 0+3=3
  3+5=8
  8+7=15
  15+11=26
  because 3,5,7,11 are prime number so ans is 26
