a. 145
b. 178
c. 176
d. 191

• actually if we split up series then we get,
  11,23,47,83,131
  from this we see that,
  23-11=12,
  47-23=24,
  83-47=36,
  131-83=48,

• solution:
  given series...11,23,47,83,131,?..
  11+12=23
  23+12+12=47
  47+12+12+12=83
  83+12+12+12+12=131
  131+12+12+12+12+12=191
  ANS=191

• 11 23 47 83 131
  11 to 23 difference is 12
  23 to 47 difference is 24
  47 to 83 difference is 36
  83 to 131 difference is 48
  131 to 191 difference is 60
  so this is the sequence of the 12 th table so answer is :191

• divide these numbers as 11 23 47 83 131 191
  in these number 23-11=12
  47-23=24
  83-47=36
  131-83=48 so from this we know that these are multiples of 12
  we know that 12*5=60 so we add 131+60=191 so answer =191

• 191 11+ 12=23 23+24=47 47+36=83 83+48=131 131+60=191
• 9 years agoHelpfull: Yes(0) No(0)
• 
  23-11=12
  47-23=24
  in this way 131-83=48 so it is multiple of 12.
  next number will be:131+(5*12)=191
• 9 years agoHelpfull: Yes(0) No(0)
• 11+12 = 23
  23+24 = 47
  47+ 36 = 83
  83+ 48 = 131
  131+60 = 191
  
  
  so answer = 191 (d)
