What is the next number of the following sequence..
1,3,8,15,27,___

• 1 3 8 15 27 46
  2 5 7 12 19
  3-1=2, 8-3=5 now add ...and so on........
  just see the above pattern ....... 3-1=2, 8-3=5 now do 2+5=7 it will give you the next no. which you have to add in the upper line and do the calculation ....your answer will be... 46 :)

• diff between numbers 1 and 3 is 2 ,3 and 8 is 5. now differences are added 2+5=7 which is the diff b/w 8 and 15. so answer is 46

• 
  1+3=4+4=8
  8+3=11+4=15
  15+8=23+4=27
  27+15=42+4=46 (ans)

• 1+3= 4 then 4+4=8
  8+3=11 nd again 4 is addae to the sum i.e 11+4=15
  similarly 8+15= 23 nd again 4 is added to it 23+4= 27
  and the last 15+27= 42 nd 4 is added to it so the next no will be 42+4= 46

• 1,3,8,15,27,46
  3-1=2
  8-3=5
  15-8=7(which is sum of above 2+5)
  27-15=12(which is sum of 5+7)
  so next number should be with diffrnce (7+12=19)
  27-x=19
  x=46

• next number is 46
  1 3 8 15 27
  Differences:
  2 5 7 12
  1+2=3
  3+5=8
  8+7=15(sum of previous two differences)
  15+12=27
  27+19=46

• the given series is 1,3,8,15,27
  difference between first two terms ie, 3-1=2
  likewise 8-3=5
  15-8=7
  27-15=12
  sum of previous two differences added to the number gives the next number in the series

• Ans is :46
  1|3|8|15|27|
  DIFFERENCE BETWEEN SERIES IS :
  2
  5
  2+5=7
  7+5=12
  12+7=19
  THEREFORE 27+19=46

• the next number is 39
• 9 years agoHelpfull: Yes(0) No(0)
• 1....3.....8....15.....27
  Diffrnc b/w 1 & 3 = 2
  Diffrnc b/w 3 & 8= 5
  Diffrnc b/w 8 & 15=7
  Diffrnc b/w 15 & 27= 12
  Series 2 +5=7 ;5+7=12; 7+12=19
  19added with 27 ...so ans will be
  19+27= 46 .......
