divya  (10 years ago)

9. The series is 6,3,3,9,12,5,7,35,8,6,2.

Next number will be: 12

Consider series as (6,3,3) ,9,(12,5,7) ,35,(8,6,2)

If we notice the pattern we find that third number is difference between the first and second number , whereas the fourth number is product of second and third number.

i.e 6-3=3, 3*3=9,
12-5=7, 7*5=35,
8-6=2 6*2=12

6)Divide the series(1/5,1/2,1/3),(2/5,1,2/3),(3/5,1 1/2,1),(4/5,....)
See the numbers in the 2nd series are twice the numbers of the 1st series.
2/5=1/5*2
1=1/2*2
2/3=1/3*2
similarly the 3rd series is thrice the 1st series and so on
so the final series will be 4*1st series
4*1/5=4/5
4*1/2=2
4*1/3=4/3
Ans:2
