2,6,5,11,26,17.........................?

• its a prime number series
  2 ,3*2 ,5,7*2,11,13*2,17
  so next number is 19*2=38

• 2,5,26 is 1 series 5=2*2+1 and 26=5*5+1
  6,11,17 is another series 11=6*2-1 17=6*3-1

• 2,6,5,14,11,26,17...
  difference between 2,5,11,17 is 3, 6,6...
  difference between 6,14,26 is.. 8,12..
  lets assume the next difference is 12 too..
  8,12,12...
  so adding, 26+12=38..
  next term is 38

• first number in the series should keep like this only..
  consider the next two numbers 6 and 5..Sum of this two numbers gives the next number 11..
  like this the addition of next two numbers 26 and 17.. gives 43.
  Hence the answer should be 43.

• 2,3*2,5,7*2,11,13*2,17,(19*2=38),23,(29*2=58)
  
  now series will be
  2,6,5,11,26,17,38,23,58
  prime no series

• this is following a prime number sequence (2 ,3*2 ,5),(11,13*2,17) so the next prime number after 17 is 19 but after three consecutive prime number one number is left so answer must be 23.

• 2, 3*2, 5, 7*2, 11, 13*2, 17, 19*2
  so answer is 38
• 8 years agoHelpfull: Yes(1) No(1)
• 2+3=6; 6-1=5
  5+9=14; 14-3=11
  11+15=26 26-9=17
  17+21=38
  
  as we can observe the pattern on the left 3,9,15,21,27....there is a difference of six .
  on the right hand side we observe the pattern 1,3,9,15,21,27......
  
  
  Therefore, the answer for this sequence is 38.
