Read Solution (Total 14)
-
- consider 3,5,2,3.5 3,(3+'2')=5,(5-'3')=2,(2+'1.5')=3.5
consider 4,6,3,4.5 4,(4+'2')=6,(6-'3')=3,(3+'1.5')=4.5
consider 1.5,..... 1.5,(1.5+'2')=3.5
answer=3.5 - 11 years agoHelpfull: Yes(25) No(10)
- divide list into 2 groups of 5 num each.
3 5 2 3.5 7(5-3=2,(5+2)/2=7)
4 6 3 4.5 9(6-4=2,(6+3)/2=4.5)
so
1.5+2=3.5
so ans is
3.5 - 11 years agoHelpfull: Yes(10) No(5)
- group first 10 numbers into 2 grps of 5
ans- 3.5 - 11 years agoHelpfull: Yes(4) No(2)
- 3.5*2=7; 4.5*2=9; 1.5*2=3; Ans 3

- ANSWER : 3.5
3,5,2,3.5,7 ,4,6,3,4.5,9 ,1.5,?
3+2=5... ,4+2=6... 1.5+2 = ?
?= 3.5 - 11 years agoHelpfull: Yes(3) No(1)
- make grps of 5 terms i.e (3,5,2,3.5,7) & (4,6,3,4.5,9)
1st term+0.5=4th term(3+0.5=3.5)(4+0.5=4.5),4th term*2=5th term also 2nd+3rd term= 5th term (3.5*2=7 & 5+2=7)(4.5*2=9)
hence 9,1.5,17.5,9.5,19 - 11 years agoHelpfull: Yes(2) No(2)
- consider 2 groups of 5 no each--
3 5 2 3.5 7 and
4 6 3 4.5 9 -- in each group , 2nd digit= 1st+2 ; 3rd=1st-1 ; 4th= 1st+0.5; last= 2nd+ 3rd... so in next series , 1st= 1.5 , so 2nd= 3.5 - 11 years agoHelpfull: Yes(2) No(0)
- divide in 3 grps ,4 in each,
2(sum of last two in each grp - 1st term in each grp)= 2nd term in each group so ans=7.5 - 11 years agoHelpfull: Yes(1) No(0)
- satya nayak can u xplain it properly
- 11 years agoHelpfull: Yes(0) No(2)
- take 1st group of 5 nums 3 5 2 3.5 7
+1 to 1st 4no's and +2 for last
then 2nd group will be like 4 6 3 4.5 9
then 3rd group is 5 7 4 5.5 11
correct me if wrong - 11 years agoHelpfull: Yes(0) No(1)

- 3, 5, 2, 3.5,7, x
+1,+1 +1,+1 ,+2 -2
4, 6, 3, 4.5,9, 1.5
x-2=1.5
x=2+1.5
x=3.5 - 10 years agoHelpfull: Yes(0) No(3)
- ( 3, 5 ,2 ) (3.5,7)
+1,+1,+1
( 4, 6, 3 ) (4.5,9)
-2.5 -2.5 -2.5
(1.5, 3.5, .5 )
4-2.5=1.5
6-2.5=3.5
ans=3.5 - 7 years agoHelpfull: Yes(0) No(1)
- answer is 3
- 7 years agoHelpfull: Yes(0) No(0)
