• 1 ans 9
  3,4.5,7,4,6,5.5,5,7.5,10,6,?
  (3,4,5,6)(4.5,6,7.5,X)

• copied Dipin's answer
  
  4> 11,8,17,14,23,24,31,32,?
  11,8,17,14,23,24,31,32,41
  
  Using alternate prime numbers in series like 11,17,23,31,41
  
  alternate prime numbers are reduced by 5
  like 8(13-5),14(19-5),24(29-5),32 (37-5),
  
  so next number is 41.
