- Ans=Next number in the series is 0.8
1.8/3=0.6
2.5/5=0.5
3.4/2=1.7
4.8/6=0.8 - 12 years agoHelpfull: Yes(62) No(4)
- 1.8,3,0.6,2.5,5,0.5,3.4,2,1.7,4.8,6,0.8

- take first 3 numbers
1.8/3=.6
likewise
2.5/5=.5
3.4/2=1.7
ans:4.8/6=.8 - 12 years agoHelpfull: Yes(8) No(0)
- ans is 0.8
- 12 years agoHelpfull: Yes(4) No(0)
- 1.8/3=0.6
2.5/5=0.5
3.4/2=1.7
4.8/6=0.8(ans) - 12 years agoHelpfull: Yes(2) No(0)
- 0.8
1.8/3=0.6
4.8/6=0.8
- 10 years agoHelpfull: Yes(1) No(0)
- 3*0.6=1.8
5*0.5=(25) means 2.5 according to question
1.7*2=(34) means 3.4 according to question
6*0.8=(48) means 4.8 according to question
Now
so ans is 0.8 - 8 years agoHelpfull: Yes(1) No(0)

Question 2) Answer 9
Explanation
------------------------------------------------------------------------------------------
3,4,5,6 is a separate series (which has no relation with the answer anyway)
set 1------> (4.5,7) diff. is 2.5 --> Decimal followed by Number
set 2------>(6,8.5) diff. is 2.5 --> Number followed by Decimal
set 3------>(7.5,10) diff. is 2.5 --> Decimal followed by Number
set 4------>(?,?) --> Number followed by Decimal(Obviously)
If you look carefully,
adding 1 to the Number in set 1(7) gives the Whole part of Decimal in set 2(8 in 8.5)
adding 1 to the Number in set 2(6) gives the Whole part of Decimal in set 3(7 in 7.5)
adding 1 to the Number in set 3(10) gives the Whole part of Decimal in set 4(11 in 11.5)
so if you have to get 11.5 as Decimal in set 4 the Number should be 9
Finally set 4------>(9,11.5)
------------------------------------------------------------------------------------------
Hence 9 is the answer
