Below a sequence of number is given, fill the blank space 1) 6, 5, 43.2 2) 5, 4, 31.25 3) 4, 3, 2

Pradyumna K S   9 years AGO

6, 5, 43.2. 6³=5×43.2
5, 4, 31.25 5³=4×31.25
4, 3, 21.33. 4³=3×21.33
3, 2, x. 3³=2×(x)
x=13.5
Therefore the missing number in the sequence is 13.5
Correct answer is option (5)

Here, the logic is 3rd number of the series=(1st number of the series)^3/(2nd number of the series).
So, from the above formula we get,
3^3/2=27/2=13.5
So, option 5)13.5 is the right answer

SHEELA S   9 years AGO

Ans is 5
bz,
6+5=11 , 43.2 is subracted by 11 so we get 32.2
then i get the difference of 0.95 between 31.25 and 32.2

5+4=9 , 31.25 is subracted by 9 so we get 22.25
then i get the difference of 0.92 between 22.25 and 21.33

4+3=7 , 21.33 is subtracted by 7 so we get 14.33
then i get the differnce of o.89 between 14.33 and 13.43

so ans is option 5(13.5)
