- 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 - 12 years agoHelpfull: Yes(19) No(10)

- +6,-12,+35
add -62 in last number
+6,-12,-27

- 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 - 12 years agoHelpfull: Yes(2) No(3)
- 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 - 12 years agoHelpfull: Yes(2) No(2)
