10,11,14,23,.......,131
what is the number in the ........?

• 50
  
  10+ 3^0= 10+1= 11
  11+ 3^1= 11+3= 14
  14+ 3^2= 14+9= 23
  23+ 3^3= 23+27=50
  50+ 3^4= 50+81=131

• Answer = 50
  
  The nth number in series is = (n-1)th number + pow(3,n-2) for n>=2
  So, 2nd term = 10 + 1 = 11
  3rd term = 11 + 3 = 14
  4th term = 14 + 9 = 23
  5th term = 23 + 27 = 50
  6th term = 50 + 81 = 131

• ans 50
  difference between 10&11 is 1=3^0
  difference between 11&14 is 3=3^1
  differeence between 14 &23 is 9=3^2
  hence next difference is 3^3=27
  hence no is 23+27=50

• 10 (1),11 (3),14 (9),23 (27), 50 (81), 131....hence 50 will be

• 11-10=1=3 power 0
  14-11 = 3 = 3 power 1
  23-14 =9
  x-23=27
  x=27+23=50
  50+81=131
