1)
38,36,76,35,114,34,..
38*1=38
38*2=76
38*3=114
38*4=152
so ans is 152

2)
18,6,24,4,30,10,12,2,6,...
18/6=3
24/46=6
30/10=3
12/2=6
6/X=3
put x is 2
so 6/2=3
hence ans is 2

4)
9,3,6,21,9,12,33,15,18,45,21,24,...
4th no - 1st no =>21-9=12
7th no - 4th no =>33-21=12
10th no - 7th no =>45-33=12
13th no -10th no =>X-45=12
put x is 57
so 57-45=12
so ans is 57

4.)(9,3,6),(21,9,12),(33,15,18),(45,21,24),..
9->3+6= 1st term-> 2nd term + 3rd term
tis applies to each grp
now for the first term of 5th grp
9=3*3
21=3*7
33=3*11
45=3*15
57=3*19
so the next term is 57

Is this solution Helpfull? Yes (5) | No   

sravs  (10 years ago)

4.ans=57
3rd term(6)+2nd term(3)=1st term(9)
1st term(9)+12=21
and so on...45+12=57

Is this solution Helpfull? Yes (2) | No   

Mainak Kumar Das  (10 years ago)

4)for every 1st,4th,7th.. posotions
9+12=21
21+12=33..
for 2nd,5th..postions
3*1=3
3*3=9
3*5=15....
for 3rd 6th..positions
3rd=1st-2nd
6th=4th=5th..
so and=
45+12=57
3*7=21
57-21=36

so series is 57,21,36

dharani  (10 years ago)

4. 9,3,6,21,9,12,33,15,18,45,21,24,...
9-3=6
21-9=12
33-15=18
45-21=24
So 3rd place series s lyk -> 6,12,18,24
Nd d 2nd place s lyk alternating multiples of 3-> 3,9,15,21
So d next series s X-27=30
So X=57
