+6,-12,+35,+6,-12,-27,+6,-12

• from the 3rd and 6th number we can calculate the 9th number of the series. subtracting 2 from the first multiplying number and adding 2 to the other multiplicand and the sign is given alternatively.
  5*7=35
  3*9=27
  1*11=11
  thus next number is +11

• don't care about +6 and -12 bcs it repeat after every 2 digit in series
  so we consider only +35 ,-27, ?
  thats is 27+35=62
  then next term is -27-62= -89

• ans will be 39
  (+6,-12),+35,(+6,-12),-27,(+6,-12),x,(+6,-12)
  35-6=+29
  -27-6=-31
  x-6=+33 [because d ans is increasing by 2 and sign is changing]
  den,
  x=39
