7,9,43,91,187,?

• correct is 7,19,43,91,187
  
  19-7= 12
  43-19= 24
  91-43= 48
  187-91=96
  
  now rhs is increasing in multiple of 2 so..
  96 * 2 = 192
  
  x- 187= 192
  x= 379
  so next term is 379

• correct series is 7,19,43,91,187,?
  pattern is(previous no*2+5)
  7*2+5=19
  19*2+5=43
  43*2+5=91

• I think the question is correct.
  (7,9),(43,91),(187,?)
  7*2-5=9
  43*2+5=91
  187*2-5=369(ans)

• ans is 379 for series 7,19,43,91,187
• 11 years agoHelpfull: Yes(3) No(0)
• Ans is 285
  take difference of consecutive no=2,32,48,96
  2*16=32+16=48(multiply 16 and add 16 )
  48*2=96+2=98(multiply 2 and add 2)
  98+187=285

• two serries...
  1st ->> 7 , 43 , 187 &
  2nd ->> 9 , 91 , --?--
  43-7=36 , 91-9=82
  36*4=144, 82*4=328
  187-43=144,419-91=328
