1)
1/2,5/4,2,11/4,7/2,...
multiply 4
1/2*4=2
5/4*4=5
2*4=8
11/4*4=11
7/2*4=14
hence 2,5,8,11,14
5-2=3
8-5=3
11-8=3
14-11=3
X-14=3
put the value of x is 17
so 17-14=3
so ans is 17

2)
0.5,1.25,2,2.75,3.5,...
1.25-0.5=0.75
2.275-1.25=1.025
3.5-2.275=0.75
X-3.5=1.025
put the value of x is 4.525
4.525-3.5=1.025
so ans is 4.525

3)
5,50,10,40,15,30,20,20,..
5,10,15,20,25
so ans is 25

4)
11,17,-6,-13,24,30,-19,-26,20,....
17-11=6
-13-(-6)=-13+6=-7
30-24=6
-26-(-19)=-26+19=-7
X-20=6
so put the value of x is 26
26-20=6
so ans is 26

sravs  (10 years ago)

1.
1/2=0.5
0.5+0.75=1.25
5/4=1.25
1.25+0.75=2
and so on
7/2=3.5+0.75=4.25=17/4
answer is 17/4

Is this solution Helpfull? Yes (3) | No   

sfsdf  (10 years ago)

1.add 3/4 to next tems to obtain the series ans is 17/4
2.0.75 is the common difference.....so the ans is 4.25
3.odd terms are multiples of 5 so ans is 25
4.the diifference between the terms is 6 and -7 alternatively ans is 26

Is this solution Helpfull? Yes (3) | No   

Khushbu  (10 years ago)

5,-,10,-,15,-,20,-,25
for 1st number there is addition of 5 in each next to next number and for second number there is subtraction of 10 in each next to next number

Shaik Feroz  (10 years ago)

1. the series can be rewritten as 2/4,5/4,8/4,11/4,14/4.
and the difference among the numerators is 3.
so the next term will be 17/4.
