what is the next number of the series
23,27,33,41,51, ,

• 27-23 = 4
  33-27 = 6
  41-33 = 8
  51-41 = 10
  63-51 = 12
  
  4,6,8,10,12 these are composite numbers
  
  so
  the series is 23,27,33,41,51,63

• 23+(4)=27+(6)=33+(8)=41+(10)=51+(12)=63
• 11 years agoHelpfull: Yes(13) No(3)
• Ans:63
  23+4=27
  27+6=33
  33+8=41
  41+10=51
  51+12=63
  each number is added with multiples of 2

• 27-23=4
  33-27=6
  41-33=8
  51-41=10
  x-51=12, there fore x=63

• it is in increasing order 2,4,6,8,10,12 so the next number is 63
• 10 years agoHelpfull: Yes(3) No(2)
• 27-23 = 4
  33-27 = 6
  41-33 = 8
  51-41 = 10
  a-51 = 12
  by solving we get
  a=63

• 63(Sixty Three) is the next no.
• 10 years agoHelpfull: Yes(3) No(0)
• 51+12=63
  63+14=77
  
• 10 years agoHelpfull: Yes(3) No(1)
• ans is 63
  
  explanation:
  difference b/w consecutive two nos in the series is multiple of 2 starting from 4.
  so , next no 'll be 63

• diff bet 1st and 2nd no is=4;
  diff bet 2nd and 3rd no is=6;
  diff bet 3rd and 4th no is=8;
  ..
  ...
  next number is 63.

• 63,
  23+4=27
  27+6=33
  33+8=41
  41+10=51
  then51+12=63

• 27-23=4,33-27=6,41-33=8,51-41=10
  eg.the series increases in AP 4,6,8,10,
  so answer is 63

• ans is 63,
  
• 11 years agoHelpfull: Yes(1) No(1)
• ans-51+12=63
• 10 years agoHelpfull: Yes(1) No(0)
• the pattern is +4,+6,+8,+10,+12
  hence the number is 51+12=63
• 10 years agoHelpfull: Yes(1) No(0)
• ans is 73
  27-23=4
  33-27=6
  41-33=8
  51-41=10
  63-51=12

• 63..bcoz diff b.w two num resultng in series as 2,4,6,8...
• 9 years agoHelpfull: Yes(0) No(0)
• the answer is 63
